MapR Technologies Tuesday released version 1.2 of its MapR Distribution for Apache Hadoop. The widgetry is imbued with more features to leverage MapReduce 2.0, when it gets here, a move meant to push the start-up way ahead of its Hadoop rivals.

Out now in an early alpha cut called Yarn, MapReduce 2.0 is meant to let Hadoop run more than just MapReduce applications on the same cluster. (Think MPI and stream processing.)

MapR, which already supports the industry-standard NFS interface as well as the Hadoop FileSystem API, means to combine MapReduce 2.0 with a robust storage services layer that provides direct access through NFS so companies can take full advantage of 2.0's next-generation Hadoop resource management framework. It expects no one else will be able to match it - at least not for some time.

The point release also expands support for C/C++ API access, provides easy-to-install packages for Mac and Windows (in addition to Linux) - no need to install third-party libraries like cygwin - and upgrades various packages such as HBase, Hive and Pig.

The company said a complete MapR 1.2 cluster is available as a free VMware virtual machine so people can experiment. It can be run on any environment including a laptop.
