Apache Hadoop 2.0 (Alpha) Released by Arun Murthy.
From the post:
As the release manager for the Apache Hadoop 2.0 release, it gives me great pleasure to share that the Apache Hadoop community has just released Apache Hadoop 2.0.0 (alpha)! While only an alpha release (read: not ready to run in production), it is still an important step forward as it represents the very first release that delivers new and important capabilities, including:
- HDFS HA (manual failover)
- NextGen MapReduce a.k.a YARN
- HDFS Federation
- Performance
- Wire-compatibility for both HDFS & YARN (via protobufs)
In addition to these new capabilities, there are several planned enhancements that are on the way from the community, including HDFS Snapshots and auto-failover for HA NameNode, along with further improvements to the stability and performance with the next generation of MapReduce (YARN). There are definitely good times ahead.
Let the good times roll!
