+<p>Apache Accumulo 1.6.3 is a maintenance release on the 1.6 version branch.
+This release contains changes from over 63 issues, comprised of bug-fixes,
+performance improvements and better test cases. </p>
+<p>Users of 1.6.0, 1.6.1, and 1.6.2 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 1.4 or 1.5 that are seeking to upgrade
+to 1.6 should consider 1.6.3 as a starting point. For information about
+improvements since Accumulo 1.5, see the <a href="http://accumulo.apache.org/release_notes/1.6.0.html">1.6.0</a>,
<a href="http://accumulo.apache.org/release_notes/1.6.1.html">1.6.1</a>, and
+<a href="http://accumulo.apache.org/release_notes/1.6.2.html">1.6.2</a> release
notes.</p>
+<h2 id="fixed-batchwriter-hold-time-error">Fixed BatchWriter hold time error</h2>
+<p>In previous releases a <code>BatchWriter</code> could fail with a
+<code>MutationsRejectedException</code> with server errors.  If inspection of
the tserver
+logs showed <code>HoldTimeoutException</code> was the cause, the workaround was
to
+increase the value of <code>general.rpc.timeout</code>.  Changing this setting
is no
+longer necessary as this bug was fixed by <a href="https://issues.apache.org/jira/browse/ACCUMULO-2388">ACCUMULO-2388</a>.</p>
+<h2 id="severe-bug-fixes">Severe bug fixes.</h2>
+<ul>
+<li><a href="https://issues.apache.org/jira/browse/ACCUMULO-3597">ACCUMULO-3597</a>
Fixed deadlock where a tablet flush and
+   metadata tablet load were waiting on each other.  This was a rare bug. If it
+   occurred it could impact the availability of Accumulo as most Accumulo
+   operations depend on metadata tablets.</li>
+<li><a href="https://issues.apache.org/jira/browse/ACCUMULO-3709">ACCUMULO-3709</a>
Fixed potential data loss bug where
+   AccumuloOutputFormat close did not rethrow exception.</li>
+<li><a href="https://issues.apache.org/jira/browse/ACCUMULO-3745">ACCUMULO-3745</a>
Fixed deadlock in SourceSwitchingIterator
+  that occured when using custom iterators that called deep copy.  This bug
+  would cause scans to hang indefinitely until the tserver was killed.</li>
+</ul>
+<h2 id="notable-bug-fixes">Notable bug fixes</h2>
+<ul>
+<li><a href="https://issues.apache.org/jira/browse/ACCUMULO-3589">ACCUMULO-3589</a>
du in shell does not check table existence</li>
+<li><a href="https://issues.apache.org/jira/browse/ACCUMULO-3692">ACCUMULO-3692</a>
Offline table disables balancing</li>
+<li><a href="https://issues.apache.org/jira/browse/ACCUMULO-3718">ACCUMULO-3718</a>
Fixed bug that prevented a Mutation from
+   being created in Scala.</li>
+<li><a href="https://issues.apache.org/jira/browse/ACCUMULO-3750">ACCUMULO-3750</a>
Fixed issue where master would perpetually
+   fail when there was a bad instance.secret setting.</li>
+<li><a href="https://issues.apache.org/jira/browse/ACCUMULO-3784">ACCUMULO-3784</a>
Fixed bug in getauths shell command where it
+   treated visibilities that differed only in case as the same.</li>
+<li><a href="https://issues.apache.org/jira/browse/ACCUMULO-3796">ACCUMULO-3796</a>
Added documentation about turning off zone
+   reclaim.  </li>
+<li><a href="https://issues.apache.org/jira/browse/ACCUMULO-3859">ACCUMULO-3859</a>
Fixed race condition that prevented table
+   constraint from loading on all servers (is this description good?)</li>
+<li><a href="https://issues.apache.org/jira/browse/ACCUMULO-3880">ACCUMULO-3880</a>
Malformed Configuration Causes tservers To Shutdown</li>
+<li><a href="https://issues.apache.org/jira/browse/ACCUMULO-3890">ACCUMULO-3890</a>
Fixed performance issue with
+   CredentialProvider.  This could degrade performance when ...</li>
+</ul>
+<h2 id="known-issues">Known Issues</h2>
+<p>During testing <a href="https://issues.apache.org/jira/browse/HDFS-8406">HDFS-8406</a>
was encountered.  To work around this issue do
+the following :</p>
+<ol>
+<li>Locate block for walog whose lease can not be recovered.</li>
+<li>Copy block into HDFS as temp file TMP_WALOG</li>
+<li>Delete the walog whose lease can not be recovered.</li>
+<li>Move TMP_WALOG to the filename of the walog deleted in the previous step.</li>
+</ol>
+<h2 id="testing">Testing</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>
