+<p>Apache Accumulo 1.7.1 is a maintenance release on the 1.7 version branch. This
+release contains changes from 55 issues, comprised of bug-fixes, performance
+improvements, build quality improvements, and more. See <a href="https://issues.apache.org/jira/browse/ACCUMULO/fixforversion/12329940">JIRA</a>
for a
+complete list.</p>
+<p>Users of any previous 1.7.x release are strongly encouraged to update as soon
+as possible to benefit from the improvements with very little concern in change
+of underlying functionality. Users of 1.6 or earlier that are seeking to
+upgrade to 1.7 should consider 1.7.1 as a starting point.</p>
+<h2 id="outstanding-known-issues">Outstanding Known Issues<a class="headerlink"
href="#outstanding-known-issues" title="Permanent link">&para;</a></h2>
+<p>Be aware that a small documentation bug exists with the compact command in the
+shell ([ACCUMULO-4138][ACCUMULO-4138]). The documentation for the begin row and
+end row should be described as exclusive and inclusive, respectively, rather
+than the incorrect description of both being inclusive.</p>
+<h2 id="highlights">Highlights<a class="headerlink" href="#highlights" title="Permanent
link">&para;</a></h2>
+<h3 id="queued-compactions-not-running">Queued Compactions Not Running<a class="headerlink"
href="#queued-compactions-not-running" title="Permanent link">&para;</a></h3>
+<p>Found and fixed a bug ([ACCUMULO-4016][ACCUMULO-4016]) in which some queued
+compactions would never run if the number of files changed while the tablet was
+queued.</p>
+<h3 id="faster-processing-of-conditional-mutations">Faster Processing of Conditional
Mutations<a class="headerlink" href="#faster-processing-of-conditional-mutations" title="Permanent
link">&para;</a></h3>
+<p>Improved ConditionalMutation processing time by a factor of 3.
+([ACCUMULO-4066][ACCUMULO-4066])</p>
+<h3 id="slow-gc-while-bulk-importing">Slow GC While Bulk Importing<a class="headerlink"
href="#slow-gc-while-bulk-importing" title="Permanent link">&para;</a></h3>
+<p>Found and worked around an issue where lots of bulk imports creating many new
+files would significantly impair the Accumulo GC service, and possibly prevent
+it from running to completion entirely. ([ACCUMULO-4021][ACCUMULO-4021])</p>
+<h3 id="improvements-in-locating-client-configuration-file">Improvements in Locating
Client Configuration File<a class="headerlink" href="#improvements-in-locating-client-configuration-file"
title="Permanent link">&para;</a></h3>
+<p>Fixed some unexpected error messages related to setting
+ACCUMULO_CLIENT_CONF_PATH, and improved the detection of the client.conf file if
+ACCUMULO_CLIENT_CONF_PATH was set to a directory containing client.conf.
+([ACCUMULO-4026][ACCUMULO-4026],[ACCUMULO-4027][ACCUMULO-4027])</p>
+<h3 id="transient-zookeeper-disconnect-causes-fate-threads-to-exit">Transient ZooKeeper
disconnect causes FATE threads to exit<a class="headerlink" href="#transient-zookeeper-disconnect-causes-fate-threads-to-exit"
title="Permanent link">&para;</a></h3>
+<p>ZooKeeper clients are expected to handle the situation where they become
+disconnected from the ZooKeeper server and must wait to be reconnected
+before continuing ZooKeeper operations.</p>
+<p>The dedicated threads running inside the Accumulo Master process for FATE
+actions had the potential unexpectedly exit in this disconnected state.
+This caused a scenario where all future FATE-based operations would
+be blocked until the Accumulo Master process was restarted. ([ACCUMULO-4060][ACCUMULO-4060])</p>
+<h3 id="incorrect-management-of-certain-thrift-rpcs">Incorrect management of certain
Thrift RPCs<a class="headerlink" href="#incorrect-management-of-certain-thrift-rpcs" title="Permanent
link">&para;</a></h3>
+<p>Accumulo relies on Apache Thrift to implement remote procedure calls between
+Accumulo services. Accumulo's use of Thrift uncovered an unfortunate situation
+where a special RPC (a "oneway" call) would leave unwanted data on the underlying
+Thrift connection. After this extra data was left on connection, all subsequent RPCs
+re-using that connection would fail with "out of sequence response" error messages.
+Accumulo would be left in a bad state until the mishandled connections were released
+or Accumulo services were restarted. ([ACCUMULO-4065][ACCUMULO-4065])</p>
+<h2 id="other-notable-changes">Other Notable Changes<a class="headerlink" href="#other-notable-changes"
title="Permanent link">&para;</a></h2>
+<ul>
+<li><a href="https://issues.apache.org/jira/browse/ACCUMULO-3509">ACCUMULO-3509</a>
Fixed some lock contention in TabletServer, preventing resource cleanup</li>
+<li>[ACCUMULO-3734][ACCUMULO-3734] Fixed quote-escaping bug in VisibilityConstraint</li>
+<li>[ACCUMULO-4025][ACCUMULO-4025] Fixed cleanup of bulk load fate transactions</li>
+<li>[ACCUMULO-4070][ACCUMULO-4070] Fixed Kerberos ticket renewal for all Accumulo services</li>
+<li>[ACCUMULO-4098][ACCUMULO-4098],[ACCUMULO-4113][ACCUMULO-4113] Fixed widespread
misuse of ByteBuffer</li>
+</ul>
+<h2 id="testing">Testing<a class="headerlink" href="#testing" title="Permanent link">&para;</a></h2>
+<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>
