<h2>New Features in Brisk 1.0 Beta 2</h2>

<p>The following new features have been added in this release:</p>

			</td>
			<td valign="top" width="370">
			<p>Add a second HDFS layer in CassandraFS for long-term data storage. This is needed because the blocks column family in CFS requires frequent compactions - Hadoop uses it during MapReduce processing to store small files and temporary data. Compaction cleans this temporary data up after it is not needed anymore. Now there is the cfs:/// and cfs-archive:/// endpoints within CFS. The blocks column family in cfs-archive:/// has compaction disabled to improve performance for static data stored in CFS.</p>

<h2>Open Issues</h2>

<p>For a description of the open issues in Brisk, see the&nbsp;Brisk Jira Project Web site.</p>

<h2>About Brisk</h2>

<p>Brisk is an open-source Hadoop and Hive distribution developed by DataStax that utilizes Apache Cassandra for its core services and storage. Brisk provides Hadoop MapReduce capabilities using CassandraFS, an HDFS-compatible storage layer inside Cassandra. By replacing HDFS with CassandraFS, users are able to leverage their current MapReduce jobs on Cassandra’s peer-to-peer, fault-tolerant, and scalable architecture. Brisk is also able to support dual workloads, allowing you to use the same cluster of machines for both real-time applications and data analytics without having to move the data around between systems.</p>

<p>Brisk is available via Apache license v2.0, and contains the following components:</p>

<ul>
	<li>Apache Hadoop 0.20.203.0 + (<a href="https://issues.apache.org/jira/browse/HADOOP-7172">HADOOP-7172</a>,&nbsp;<a href="https://issues.apache.org/jira/browse/HADOOP-5759">HADOOP-5759</a>,&nbsp;<a href="https://issues.apache.org/jira/browse/HADOOP-7255">HADOOP-7255</a>)</li>
	<li>Cassandra 0.8.1</li>
	<li>Apache Hive 0.7</li>
	<li>Apache Pig 0.8.3</li>
</ul>
