    Release 1.1.2 available

    2013 Feb 15

    Point release for the 1.1.X line. Bug fixes and improvements, as documented in the Hadoop 1.1.2 Release Notes.

    Release 2.0.3-alpha available

    2013 Feb 14

    This is the latest (alpha) version in the hadoop-2.x series.

    This release delivers significant major features and stability over previous releases in hadoop-2.x series:

    • QJM for HDFS HA for NameNode
    • Multi-resource scheduling (CPU and memory) for YARN
    • YARN ResourceManager Restart
    • Significant stability at scale for YARN (over 30,000 nodes and 14 million applications so far, at time of release)

    This release, like previous releases in hadoop-2.x series is still considered alpha primarily since some of APIs aren’t fully-baked and we expect some churn in future. Furthermore, please note that there are some API changes from previous hadoop-2.0.2-alpha release and applications will need to recompile against hadoop-2.0.3-alpha.

    Please see the Hadoop 2.0.3-alpha Release Notes for details.
