<h2>Spark Release 0.6.2</h2>
<p>Spark 0.6.2 is a maintenance release that contains several bug fixes and usability improvements. You can download it as a <a href="http://spark-project.org/download/spark-0.6.2-sources.tgz">source package</a> (2.5 MB tar.gz) or <a href="http://spark-project.org/download/spark-0.6.2-prebuilt.tgz">prebuilt package</a> (48 MB tar.gz).</p>
<p>We recommend that all Spark 0.6 users update to this maintenance release.</p>
<p>The fixes and improvements in this version include:</p>
<ul>
<li>A number of fault tolerance fixes regarding detecting dead nodes, handling missing map output fetches, and allowing failed nodes to rejoin the cluster</li>
<li>Documentation fixes that clarify the configuration for the standalone mode and improve the quick start instructions</li>
<li>A connection reuse bug fix that improves shuffle performance</li>
<li>Support for launching a cluster across multiple availability zones in the EC2 scripts</li>
<li>Support for deleting security groups when an EC2 cluster is terminated</li>
<li>Improved memory configuration for the standalone deploy cluster daemons: instead of using <code>SPARK_MEM</code> for their memory, which often led people to give them much more memory than they intended, they now use a separate variable, <code>SPARK_DAEMON_MEMORY</code>, with a reasonable default of 512 MB</li>
<li>Fixes to the Windows run scripts for Spark</li>
<li>Better detection of a machine's external IP address</li>
<li>Several small optimizations and bug fixes</li>
</ul>
<p>In total, eleven people contributed to this release:</p>
<ul>
<li>Stephen Haberman (bug fix)</li>
<li>Shane Huang (shuffle fix)</li>
<li>Fernand Pajot (bug fix)</li>
<li>Andrew Psaltis (bug fix)</li>
<li>Imran Rashid (standalone cluster, bug fix)</li>
<li>Charles Reiss (fault recovery fixes, node re-registration, tests)</li>
<li>Josh Rosen (fault recovery, Java API fixes, deploy scripts)</li>
<li>Peter Sankauskas (EC2 scripts)</li>
<li>Lee Moon Soo (bug fix)</li>
<li>Patrick Wendell (bugs, docs)</li>
<li>Matei Zaharia (fault recovery, UI, docs, bug fixes)</li>
</ul>
