+          
+          <p>06 Sep 2016</p>
+
+<p>Apache Accumulo 1.8.0 is a significant release that includes many important
+milestone features which expand the functionality of Accumulo. These include
+features related to security, availability, and extensibility. Over
+350 JIRA issues were resolved in this version. This includes over
+200 bug fixes and 71 improvements and 4 new features. See <a href="https://issues.apache.org/jira/secure/ReleaseNote.jspa?projectId=12312121&amp;version=12329879">JIRA</a>
+for the complete list.</p>
+
+<p>Below are resources for this release:</p>

+<ul>

+  <li><a href="/1.8/apidocs">Javadocs</a></li>
+  <li><a href="/1.8/examples">Examples</a></li>
+</ul>
+
+<p>In the context of Accumulo’s <a href="http://semver.org">Semantic Versioning</a> <a href="https://github.com/apache/accumulo/blob/1.8/README.md#api">guidelines</a>,
+this is a “minor version”. This means that new APIs have been created, some
+deprecations may have been added, but no deprecated APIs have been removed.
+Code written against 1.7.x should work against 1.8.0 – binary compatibility
+has been preserved with one exception of an already-deprecated Mock Accumulo
+utility class. As always, the Accumulo developers take API compatibility
+very seriously and have invested much time to ensure that we meet the promises set forth to our users.</p>
+
+<h2 id="major-changes">Major Changes</h2>
+
+<h3 id="speed-up-wal-roll-overs">Speed up WAL roll overs</h3>
+
+<p>Performance of writing mutations is improved by refactoring the
+bookeeping required for Write-Ahead Log (WAL) files and by creating a
+standby WAL for faster switching when the log is full. This was a
+substantial refactor in the way WALs worked, but smoothes overall
+ingest performance in addition to provides a increase in write speed
+as shown by the simple test below. The top entry is before
+<a href="https://issues.apache.org/jira/browse/ACCUMULO-3423">ACCUMULO-3423</a> and the bottom graph is after the
+refactor.</p>
+
+<p><img src="https://issues.apache.org/jira/secure/attachment/12705402/WAL-slowdown-graphs.jpg" alt="Graph of WAL speed up after ACCUMULO-3423" title="Graph of WAL speed up after ACCUMULO-3423" /></p>
+
+<h3 id="user-level-api-for-rfile">User level API for RFile</h3>
+
+<p>Previously the only public API available to write RFiles was via the AccumuloFileOutputFormat. There was no way to read RFiles in the public
+API. <a href="https://issues.apache.org/jira/browse/ACCUMULO-4165">ACCUMULO-4165</a> exposes a brand new public <a href="../1.8/apidocs/org/apache/accumulo/core/client/rfile/RFile.html">API</a> for reading and writing RFiles as well as cleans up some of the internal APIs.</p>
+
+<h3 id="suspend-tablet-assignment-for-rolling-restarts">Suspend Tablet assignment for rolling restarts</h3>
+
+<p>When a tablet server dies, Accumulo attempted to reassign the tablets as quickly as possible to maintain availability.
+A new configuration property <code class="highlighter-rouge">table.suspend.duration</code> (with a default of zero seconds) now controls how long to wait before reassigning
+a tablet from a dead tserver. The property is configurable via the
+Accumulo shell, so you can set it, do a rolling restart, and then
+set it back to 0. A new state as introduced, TableState.SUSPENDED to support this feature. By default, metadata tablet
+reassignment is not suspended, but that can also be changed with the <code class="highlighter-rouge">master.metadata.suspendable</code> property that is false by
+default. Root tablet assignment can not be suspended. See <a href="https://issues.apache.org/jira/browse/ACCUMULO-4353">ACCUMULO-4353</a> for more info.</p>
+
+<h3 id="run-multiple-tablet-servers-on-one-node">Run multiple Tablet Servers on one node</h3>
+
+<p><a href="https://issues.apache.org/jira/browse/ACCUMULO-4328">ACCUMULO-4328</a> introduces the capability of running multiple tservers on a single node. This is intended for nodes with a large
+amounts of memory and/or disk. This feature is disabled by default. There are several related tickets: <a href="https://issues.apache.org/jira/browse/ACCUMULO-4072">ACCUMULO-4072</a>, <a href="https://issues.apache.org/jira/browse/ACCUMULO-4331">ACCUMULO-4331</a>
+and <a href="https://issues.apache.org/jira/browse/ACCUMULO-4406">ACCUMULO-4406</a>. Note that when this is enabled, the names of the log files change. Previous log file names were defined in the
+generic_logger.xml as <code class="highlighter-rouge">${org.apache.accumulo.core.application}_{org.apache.accumulo.core.ip.localhost.hostname}.log</code>.
+The files will now include the instance id after the application with
+<code class="highlighter-rouge">${org.apache.accumulo.core.application}_${instance}_${org.apache.accumulo.core.ip.localhost.hostname}.log</code>.</p>
+
+<p>For example: tserver_host.domain.com.log will become tserver_1_host.domain.log when multiple TabletServers
+are run per host. The same change also applies to the debug logs provided in the example configurations. The log
+names do not change if this feature is not used.</p>
+
+<h3 id="rate-limiting-major-compactions">Rate limiting Major Compactions</h3>
+
+<p>Major Compactions can significantly increase the amount of load on
+TabletServers. <a href="https://issues.apache.org/jira/browse/ACCUMULO-4187">ACCUMULO-4187</a> restricts the rate at which data is
+read and written when performing major compactions. This has a direct
+effect on the IO load caused by major compactions with a similar
+effect on the CPU utilization. This behavior is controlled by a new
+property <code class="highlighter-rouge">tserver.compaction.major.throughput</code> with a defaults of 0B
+which disables the rate limiting.</p>
+
+<h3 id="table-sampling">Table Sampling</h3>
+
+<p>Queryable sample data was added by <a href="https://issues.apache.org/jira/browse/ACCUMULO-3913">ACCUMULO-3913</a>.  This allows users to configure a pluggable
+function to generate sample data.  At scan time, the sample data can optionally be scanned.
+Iterators also have access to sample data.  Iterators can access all data and sample data, this
+allows an iterator to use sample data for query optimizations.  The new user level RFile API
+supports writing RFiles with sample data for bulk import.</p>
+
+<p>A simple configurable sampler function is included with Accumulo.  This sampler uses hashing and
+can be configured to use a subset of Key fields.  For example if it was desired to have entire rows
+in the sample, then this sampler would be configured to hash+mod the row.   Then when a row is
+selected for the sample, all of its columns and all of its updates will be in the sample data.
+Another scenario is one in which a document id is in the column qualifier.  In this scenario, one
+would either want all data related to a document in the sample data or none.  To achieve this, the
+sample could be configured to hash+mod on the column qualifier.  See the sample <a href="../1.8/examples/sample">Readme
+example</a> and javadocs on the new APIs for more information.</p>
+
+<p>For sampling to work, all tablets scanned must have pre-generated sample data that was generated in
+the same way.  If this is not the case then scans will fail.  For existing tables, samples can be
+generated by configuring sampling on the table and compacting the table.</p>
+
+<h3 id="upgrade-to-apache-thrift-093">Upgrade to Apache Thrift 0.9.3</h3>
+
+<p>Accumulo relies on Apache Thrift to implement remote procedure calls
+between Accumulo services. Ticket <a href="https://issues.apache.org/jira/browse/ACCUMULO-4077">ACCUMULO-4077</a>
+updates our dependency to 0.9.3. See the
+<a href="https://github.com/apache/thrift/blob/0.9.3/CHANGES">Apache Thrift 0.9.3 Release Notes</a> for details on
+the changes to Thrift.  <strong>NOTE:</strong> The Thrift 0.9.3 Java library is not
+compatible other versions of Thrift. Applications running against Accumulo
+1.8 must use Thrift 0.9.3. Different versions of Thrift on the classpath
+will not work.</p>
+
+<h3 id="iterator-test-harness">Iterator Test Harness</h3>
+
+<p>Users often write a new iterator without fully understanding its limits and lifetime. Previously, Accumulo did
+not provide any means in which a user could test iterators to catch common issues that only become apparent
+in multi-node production deployments. <a href="https://issues.apache.org/jira/browse/ACCUMULO-626">ACCUMULO-626</a> provides a framework and a collection of initial tests
+which can be used to simulate common issues with Iterators that only appear in production deployments. This test
+harness can be used directly by users as a supplemental tool to unit tests and integration tests with MiniAccumuloCluster.</p>
+
+<p>Please see the <a href="../1.8/accumulo_user_manual.html#_iterator_testing">Accumulo User Manual chapter on Iterator Testing</a> for more information</p>
+
+<h3 id="default-port-for-monitor-changed-to-9995">Default port for Monitor changed to 9995</h3>
+
+<p>Previously, the default port for the monitor was 50095. You will need to update your links to point to port 9995. The default
+port for the GC process was also changed from 50091 to 9998, although this an RPC port used internally and automatically discovered.
+These default ports were changed because the previous defaults fell in the Linux Ephemeral port range. This means that the operating
+system, when a port in this range was unusued, would allocate this port for dynamic network communication. This has the side-effect of
+temporal bind issues when trying to start these services (as the operating
+system might have allocated them elsewhere). By moving these
+defaults out of the ephemeral range, we can guarantee that the Monitor and GC
+will reliably start. These values are still configurable by setting
+<code class="highlighter-rouge">monitor.port.client</code>and <code class="highlighter-rouge">gc.port.client</code> in the accumulo-site.xml.</p>

+
+<p>Each unit and functional test only runs on a single node, while the RandomWalk
+and Continuous Ingest tests run on any number of nodes. <em>Agitation</em> refers to
+randomly restarting Accumulo processes and Hadoop Datanode processes, and, in
+HDFS High-Availability instances, forcing NameNode failover.</p>

-          <h1 class="title">Apache Accumulo 1.5.1 Release Notes</h1>
-          
-          <p>Apache Accumulo 1.5.1 is a maintenance release on the 1.5 version branch.
-This release contains changes from over 200 issues, comprised of bug fixes
-(client side and server side), new test cases, and updated Hadoop support
-contributed by over 30 different contributors and committers.
-As this is a maintenance release, Apache Accumulo 1.5.1 has no client API 
-incompatibilities over Apache Accumulo 1.5.0 and requires no manual upgrade 
-process. Users of 1.5.0 are strongly encouraged to update as soon as possible 
-to benefit from the improvements.</p>
-
-<h2 id="notable-improvements">Notable Improvements</h2>
-
-<p>While new features are typically not added in a bug-fix release as 1.5.1, the
-community does create a variety of improvements that are API compatible. Contained
-here are some of the more notable improvements.</p>
-
-<h3 id="permgen-leak-from-client-api">PermGen Leak from Client API</h3>
-
-<p>Accumulo’s client code creates background threads that users presently cannot 
-stop through the API. This is quick to cause problems when invoking the Accumulo
-API in application containers such as Apache Tomcat or JBoss and repeatedly 
-redeploying an application. <a href="https://issues.apache.org/jira/browse/ACCUMULO-2128">ACCUMULO-2128</a> introduces a static utility, 
-org.apache.accumulo.core.util.CleanUp, that users can invoke as part of a 
-teardown hook in their container that will stop these threads and avoid 
-the eventual OutOfMemoryError “PermGen space”.</p>
-
-<h3 id="prefer-ipv4-when-starting-accumulo-processes">Prefer IPv4 when starting Accumulo processes</h3>
-
-<p>While Hadoop <a href="https://wiki.apache.org/hadoop/HadoopIPv6">does not support IPv6 networks</a>, attempting to run on a 
-system that does not have IPv6 completely disabled can cause strange failures.
-<a href="https://issues.apache.org/jira/browse/ACCUMULO-2262">ACCUMULO-2262</a> invokes the JVM-provided configuration parameter at process
-startup to prefer IPv4 over IPv6.</p>
-
-<h3 id="memory-units-in-configuration">Memory units in configuration</h3>
-
-<p>In previous versions, units of memory had to be provided as upper-case (e.g. ‘2G’, not ‘2g’).
-Additionally, a non-intuitive error was printed when a lower-case unit was provided.
-<a href="https://issues.apache.org/jira/browse/ACCUMULO-1933">ACCUMULO-1933</a> allows lower-case memory units in all Accumulo configurations.</p>
-
-<h3 id="apache-thrift-maximum-frame-size">Apache Thrift maximum frame size</h3>
-
-<p>Apache Thrift is used as the internal RPC service. <a href="https://issues.apache.org/jira/browse/ACCUMULO-2360">ACCUMULO-2360</a> allows 
-users to configure the maximum frame size an Accumulo server will read. This 
-prevents non Accumulo client from connecting and causing memory exhaustion.</p>
-
-<h3 id="multitablebatchwriter-concurrency">MultiTableBatchWriter concurrency</h3>
-
-<p>The MultiTableBatchWriter is a class which allows multiple tables to be written to
-from a single object that maintains a single buffer for caching Mutations across all tables. This is desirable
-as it greatly simplifies the JVM heap usage from caching Mutations across
-many tables. Sadly, in Apache Accumulo 1.5.0, concurrent access to a single MultiTableBatchWriter
-heavily suffered from synchronization issues. <a href="https://issues.apache.org/jira/browse/ACCUMULO-1833">ACCUMULO-1833</a> introduces a fix
-which alleviates the blocking and idle-wait that previously occurred when multiple threads accessed
-a single MultiTableBatchWriter instance concurrently.</p>
-
-<h3 id="hadoop-versions">Hadoop Versions</h3>
-
-<p>Since Apache Accumulo 1.5.0 was released, Apache Hadoop 2.2.0 was also released
-as the first generally available (GA) Hadoop 2 release. This was a very exciting release
-for a number of reasons, but this also caused additional effort on Accumulo’s part to
-ensure that Apache Accumulo continues to work across multiple Hadoop versions. Apache Accumulo 1.5.1
-should function with any recent Hadoop 1 or Hadoop 2 without any special steps, tricks or instructions
-required.</p>
-
-<h2 id="notable-bug-fixes">Notable Bug Fixes</h2>
-
-<p>As with any Apache Accumulo release, we have numerous bug fixes that have been fixed. Most
-are very subtle and won’t affect the common user; however, some notable bugs were resolved 
-as a part of 1.5.1 that are rather common.</p>
-
-<h3 id="failure-of-zookeeper-server-in-quorum-kills-connected-accumulo-services">Failure of ZooKeeper server in quorum kills connected Accumulo services</h3>
-
-<p>Apache ZooKeeper provides a number of wonderful features that Accumulo uses to accomplish
-a variety of tasks, most notably a distributed locking service. Typically, multiple ZooKeeper
-servers are run to provide resilience against a certain number of node failures. <a href="https://issues.apache.org/jira/browse/ACCUMULO-1572">ACCUMULO-1572</a>
-resolves an issue where Accumulo processes would kill themselves when the ZooKeeper server they
-were communicating with died instead of failing over to another ZooKeeper server in the quorum.</p>
-
-<h3 id="monitor-table-state-isnt-updated">Monitor table state isn’t updated</h3>
-
-<p>The Accumulo Monitor contains a column for the state of each table in the Accumulo instance.
-The previous resolution was to restart the Monitor process when it got in this state.
-<a href="https://issues.apache.org/jira/browse/ACCUMULO-1920">ACCUMULO-1920</a> resolves an issue where the Monitor would not see updates from ZooKeeper.</p>
-
-<h3 id="two-locations-for-the-same-extent">Two locations for the same extent</h3>
-
-<p>The !METADATA table is the brains behind the data storage for each table, tracking information
-like which files comprise a Tablet, and which TabletServers are hosting which Tablets. <a href="https://issues.apache.org/jira/browse/ACCUMULO-2057">ACCUMULO-2057</a>
-fixes an issue where the !METADATA table contained multiple locations (hosting server) for
-a single Tablet.</p>
-
-<h3 id="deadlock-on-metadata-tablet-unload">Deadlock on !METADATA tablet unload</h3>
-
-<p>Tablets are unloaded, typically, when a shutdown request is issued. <a href="https://issues.apache.org/jira/browse/ACCUMULO-1143">ACCUMULO-1143</a> resolves
-a potential deadlock issue when a merging-minor compaction is issued to flush in-memory data
-to disk before unloading a Tablet.</p>
-
-<h3 id="other-notable-fixes">Other notable fixes</h3>

-  <li><a href="https://issues.apache.org/jira/browse/ACCUMULO-1630">ACCUMULO-1630</a> Fixed GC to interpret any IP/hostname.</li>
-</ul>
-
-<h2 id="known-issues">Known Issues</h2>
-
-<p>When using Accumulo 1.5 and Hadoop 2, Accumulo will call hsync() on HDFS.
-Calling hsync improves durability by ensuring data is on disk (where other older 
-Hadoop versions might lose data in the face of power failure); however, calling
-hsync frequently does noticably slow writes. A simple work around is to increase 
-the value of the tserver.mutation.queue.max configuration parameter via accumulo-site.xml.</p>
-
-<p>A value of “4M” is a better recommendation, and memory consumption will increase by
-the number of concurrent writers to that TabletServer. For example, a value of 4M with
-50 concurrent writers would equate to approximately 200M of Java heap being used for
-mutation queues.</p>
-
-<p>For more information, see <a href="https://issues.apache.org/jira/browse/ACCUMULO-1950">ACCUMULO-1950</a> and <a href="https://issues.apache.org/jira/browse/ACCUMULO-1905?focusedCommentId=13915208&amp;page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-13915208">this comment</a>.</p>

-
-<h2 id="testing">Testing</h2>
-
-<p>Below is a list of all platforms that 1.5.1 was tested against by developers. Each Apache Accumulo release
-has a set of tests that must be run before the candidate is capable of becoming an official release. That list includes the following:</p>
-
-<ol>
-  <li>Successfully run all unit tests</li>
-  <li>Successfully run all functional test (test/system/auto)</li>
-  <li>Successfully complete two 24-hour RandomWalk tests (LongClean module), with and without “agitation”</li>
-  <li>Successfully complete two 24-hour Continuous Ingest tests, with and without “agitation”, with data verification</li>
-  <li>Successfully complete two 72-hour Continuous Ingest tests, with and without “agitation”</li>
-</ol>
-
-<p>Each unit and functional test only runs on a single node, while the RandomWalk and Continuous Ingest tests run 
-on any number of nodes. <em>Agitation</em> refers to randomly restarting Accumulo processes and Hadoop Datanode processes,
-and, in HDFS High-Availability instances, forcing NameNode failover.</p>

-          
-          <p>Apache Accumulo 1.5.2 is a maintenance release on the 1.5 version branch.
-This release contains changes from over 100 issues, comprised of bug fixes
-(client side and server side), new test cases, and updated Hadoop support
-contributed by over 30 different contributors and committers.
-As this is a maintenance release, Apache Accumulo 1.5.2 has no client API 
-incompatibilities over Apache Accumulo 1.5.0 and 1.5.1 and requires no manual upgrade 
-process. Users of 1.5.0 or 1.5.1 are strongly encouraged to update as soon as possible 
-to benefit from the improvements.</p>
-
-<p>Users who are new to Accumulo are encouraged to use a 1.6 release as opposed
-to the 1.5 line as development has already shifted towards the 1.6 line. For those
-who cannot or do not want to upgrade to 1.6, 1.5.2 is still an excellent choice
-over earlier versions in the 1.5 line.</p>
-
-<h2 id="performance-improvements">Performance Improvements</h2>
-
-<p>Apache Accumulo 1.5.2 includes a number of performance-related fixes over previous versions.</p>
-
-<h3 id="write-ahead-log-sync-performance">Write-Ahead Log sync performance</h3>
-
-<p>The Write-Ahead Log (WAL) files are used to ensure durability of updates made to Accumulo.
-A sync is called on the file in HDFS to make sure that the changes to the WAL are persisted
-to disk, which allows Accumulo to recover in the case of failure. <a href="https://issues.apache.org/jira/browse/ACCUMULO-2766">ACCUMULO-2766</a> fixed
-an issue where an operation against a WAL would unnecessarily wait for multiple syncs, slowing
-down the ingest on the system.</p>
-
-<h3 id="minor-compactions-not-aggressive-enough">Minor-Compactions not aggressive enough</h3>
-
-<p>On a system with ample memory provided to Accumulo, long hold-times were observed which
-blocks the ingest of new updates. Trying to free more server-side memory by running minor
-compactions more frequently increased the overall throughput on the node. These changes
-were made in <a href="https://issues.apache.org/jira/browse/ACCUMULO-2905">ACCUMULO-2905</a>.</p>
-
-<h3 id="heapiterator-optimization">HeapIterator optimization</h3>
-
-<p>Iterators, a notable feature of Accumulo, are provided to users as a server-side programming
-construct, but are also used internally for numerous server operations. One of these system iterator 
-is the HeapIterator which implements a PriorityQueue of other Iterators. One way this iterator is
-used is to merge multiple files in HDFS to present a single, sorted stream of Key-Value pairs. <a href="https://issues.apache.org/jira/browse/ACCUMULO-2827">ACCUMULO-2827</a>
-introduces a performance optimization to the HeapIterator which can improve the speed of the
-HeapIterator in common cases.</p>
-
-<h3 id="write-ahead-log-sync-implementation">Write-Ahead log sync implementation</h3>
-
-<p>In Hadoop-2, two implementations of sync are provided: hflush and hsync. Both of these
-methods provide a way to request that the datanodes write the data to the underlying
-medium and not just hold it in memory (the <em>fsync</em> syscall). While both of these methods
-inform the Datanodes to sync the relevant block(s), <em>hflush</em> does not wait for acknowledgement
-from the Datanodes that the sync finished, where <em>hsync</em> does. To provide the most reliable system
-“out of the box”, Accumulo defaults to <em>hsync</em> so that your data is as secure as possible in 
-a variety of situations (notably, unexpected power outages).</p>
-
-<p>The downside is that performance tends to suffer because waiting for a sync to disk is a very
-expensive operation. <a href="https://issues.apache.org/jira/browse/ACCUMULO-2842">ACCUMULO-2842</a> introduces a new system property, tserver.wal.sync.method,
-that lets users to change the HDFS sync implementation from <em>hsync</em> to <em>hflush</em>. Using <em>hflush</em> instead
-of <em>hsync</em> may result in about a 30% increase in ingest performance.</p>
-
-<p>For users upgrading from Hadoop-1 or Hadoop-0.20 releases, <em>hflush</em> is the equivalent of how
-sync was implemented in these older versions of Hadoop and should give comparable performance.</p>
-
-<h3 id="server-side-mutation-queue-size">Server-side mutation queue size</h3>
-
-<p>When users desire writes to be as durable as possible, using <em>hsync</em>, the ingest performance
-of the system can be improved by increasing the tserver.mutation.queue.max property. The cost
-of this change is that it will cause TabletServers to use additional memory per writer. In 1.5.1,
-the value of this parameter defaulted to a conservative 256K, which resulted in sub-par ingest
-performance.</p>
-
-<p>1.5.2 and <a href="https://issues.apache.org/jira/browse/ACCUMULO-3018">ACCUMULO-3018</a> increases this buffer to 1M which has a noticeable positive impact on
-ingest performance with a minimal increase in TabletServer memory usage.</p>
-
-<h2 id="notable-bug-fixes">Notable Bug Fixes</h2>
-
-<h3 id="fixes-mapreduce-package-name-change">Fixes MapReduce package name change</h3>
-
-<p>1.5.1 inadvertently included a change to RangeInputSplit which created an incompatibility
-with 1.5.0. The original class has been restored to ensure that users accessing
-the RangeInputSplit class do not have to alter their client code. See <a href="https://issues.apache.org/jira/browse/ACCUMULO-2586">ACCUMULO-2586</a> for
-more information</p>
-
-<h3 id="add-configurable-maximum-frame-size-to-apache-thrift-proxy">Add configurable maximum frame size to Apache Thrift proxy</h3>
-
-<p>The Thrift proxy server was subject to memory exhaustion, typically
-due to bad input, where the server would attempt to allocate a very large
-buffer and die in the process. <a href="https://issues.apache.org/jira/browse/ACCUMULO-2658">ACCUMULO-2658</a> introduces a configuration
-parameter, like <a href="https://issues.apache.org/jira/browse/ACCUMULO-2360">ACCUMULO-2360</a>, to prevent this error.</p>
-
-<h3 id="offline-tables-can-prevent-tablet-balancing">Offline tables can prevent tablet balancing</h3>
-
-<p>Before 1.5.2, when a table with many tablets was created, ingested into, and
-taken offline, tablet balancing may have stoppped. This would happen if there
-were tablet migrations for the table, because the migrations couldn’t occur.
-The balancer will not run when there are outstanding migrations; therefore, a
-system could become unbalanced. <a href="https://issues.apache.org/jira/browse/ACCUMULO-2694">ACCUMULO-2694</a> introduces a fix to ensure
-that offline tables do not block balancing and improves the server-side
-logging.</p>
-
-<h3 id="miniaccumulocluster-process-management">MiniAccumuloCluster process management</h3>
-
-<p>MiniAccumuloCluster had a few issues which could cause deadlock or a method that
-never returns. Most of these are related to management of the Accumulo processes
-(<a href="https://issues.apache.org/jira/browse/ACCUMULO-2764">ACCUMULO-2764</a>, <a href="https://issues.apache.org/jira/browse/ACCUMULO-2985">ACCUMULO-2985</a>, and <a href="https://issues.apache.org/jira/browse/ACCUMULO-3055">ACCUMULO-3055</a>).</p>
-
-<h3 id="iteratorsettings-not-correctly-serialized-in-rangeinputsplit">IteratorSettings not correctly serialized in RangeInputSplit</h3>
-
-<p>The Writable interface methods on the RangeInputSplit class accidentally omitted
-calls to serialize the IteratorSettings configured for the Job. <a href="https://issues.apache.org/jira/browse/ACCUMULO-2962">ACCUMULO-2962</a>
-fixes the serialization and adds some additional tests.</p>
-
-<h3 id="constraint-violation-causes-hung-scans">Constraint violation causes hung scans</h3>
-
-<p>A failed bulk import transaction had the ability to create an infinitely retrying
-loop due to a constraint violation. This directly prevents scans from completing,
-but will also hang compactions. <a href="https://issues.apache.org/jira/browse/ACCUMULO-3096">ACCUMULO-3096</a> fixes the issue so that the
-constraint no longer hangs the entire system.</p>
