I'm very happy announce that the Apache Hadoop community has released hadoop-2.1.0-beta, the beta release of Apache Hadoop 2.x.
Users are encouraged to immediately move to hadoop-2.1.0-beta since this release is significantly more stable and has completley whetted set of APIs and wire-protocols for future compatibility.
In addition, this release has a number of other significant highlights:
• API & protocol stabilization for both HDFS & YARN
• Binary Compatibility for MapReduce applications built on hadoop-1.x
• Support for running Hadoop on Microsoft Windows
• HDFS Snapshots
• Substantial amount of integration testing with rest of projects in the ecosystem
Please see the Apache Hadoop 2.1.0-beta Release Notes for details.
With the Apache Hadoop 2.x beta release out of the door, we should follow up quickly with a bug-fix release (hadoop-2.1.1-beta) and then with a hadoop-2.2.0 GA release in the next few weeks.
Please see this discussion on the developer mailing lists for more details: http://s.apache.org/yag
