 <p>Apache Accumulo 1.6.0 adds some major new features and fixes many bugs.  This release contains changes from 609 issues contributed by 36 contributors and committers.  </p>
 <p>Accumulo 1.6.0 runs on Hadoop 1, however Hadoop 2 with HA namenode is recommended for production systems.  In addition to HA, Hadoop 2 also offers better data durability guarantees, in the case when nodes lose power, than Hadoop 1.</p>

 <p>Multiple bug-fixes were made to support running Accumulo over multiple HDFS instances using ViewFS. <a href="https://issues.apache.org/jira/browse/ACCUMULO-2047" title="Failures using viewfs with multiple namenodes">ACCUMULO-2047</a> is the parent

+<p>This version of Accumulo is accompanied by a new maven plugin for testing client apps (<a href="https://issues.apache.org/jira/browse/ACCUMULO-1030" title="Create a Maven plugin to run MiniAccumuloCluster for integration testing">ACCUMULO-1030</a>). You can execute the accumulo-maven-plugin inside your project by adding the following to your pom.xml's build plugins section:</p>

+<p>This plugin is designed to work in conjunction with the maven-failsafe-plugin. A small test instance of Accumulo will run during the pre-integration-test phase of the Maven build lifecycle, and will be stopped in the post-integration-test phase. Your integration tests, executed by maven-failsafe-plugin can access this instance with a MiniAccumuloInstance connector (the plugin uses MiniAccumuloInstance, internally), as in the following example:</p>

+<p>This plugin is quite limited, currently only supporting an instance name and a root user password as configuration parameters. Improvements are expected in future releases, so feedback is welcome and appreciated (file bugs/requests under the "maven-plugin" component in the Accumulo JIRA).</p>
 <h3 id="packaging">Packaging</h3>
 <p>One notable change that was made to the binary tarball is the purposeful omission of a pre-built copy of the Accumulo "native map" library.
 This shared library is used at ingest time to implement an off-JVM-heap sorted map that greatly increases ingest throughput while side-stepping
