Hadoop 2 is finally GA

We have been hearing about things like YARN and high availability for a few years — they’ve even been incorporated into some commercial Hadoop distributions — but now they’re finally part of the official Apache Hadoop code base. Technically version 2.2.0, “The project’s latest release marks a major milestone more than four years in the making, and has achieved the level of stability and enterprise-readiness to earn the General Availability designation,” according to an Apache Software Foundation press release.
