The free MapR M3 Edition includes HBase, Pig, Hive, Mahout, Cascading, Sqoop, Flume and other Hadoop-related components for unlimited production use. MapR M3 will be bundled with Ubuntu 12.04 LTS and 12.10 via the Ubuntu Partner Archive. MapR also announced that the source code for the component packages of the MapR Distribution for Apache Hadoop is now publicly available on GitHub.
MapR is the only distribution that enables Linux applications and commands to access data directly in the cluster via the NFS interface that is available with all MapR Editions. The MapR M5 and M7 Editions for Apache Hadoop, which provide enterprise-grade features for HBase and Hadoop such as mirroring, snapshots, NFS HA and data placement control, will also be certified for Ubuntu.
Now, as you get Hadoop integrated natively with Ubuntu, it’s a lot easier to install it and go. No more unnecessary downloads and wacky configuration steps. And the best part is the NFS interface available with MapR’s distribution that enables other Linux commands and application to access the cluster data directly. The Ubuntu/MapR package will be available through the Ubuntu Partner Archive for 12.04 LTS and 12.10 releases of Ubuntu on the official website starting from April 25, 2013.
