Announcing Apache Hadoop 2.6.0 by Arun Murthy.
From the post:
It gives me great pleasure to announce that the Apache Hadoop community has released Apache Hadoop 2.6.0 !
In particular, we are excited about three major pieces in this release: heterogeneous storage in HDFS with SSD & Memory tiers, support for long-running services in YARN and rolling upgrades—the ability to upgrade your cluster software and restart upgraded nodes without taking the cluster down or losing work in progress. With YARN as its architectural center, Hadoop continues to attract new engines to run within the data platform, as organizations want to efficiently store their data in a single repository and interact with it simultaneously in different ways.
Many thanks to all of the contributors and committers who collaborated on this version and resolved a total of nearly 900 JIRA issues across four areas:
- Hadoop Common: 231 JIRAs resolved
- Hadoop HDFS: 305 JIRAs resolved
- Hadoop YARN: 290 JIRAs resolved
- Hadoop MapReduce: 70 JIRAs resolved
Highlights for Apache Hadoop 2.6.0
Here are some details about the most important features. For the complete list of features, improvements and bug fixes, see the sidebar and the release notes.

The post includes a nifty PNG file that lists the major issues with what I think were intended to be links to JIRA issues. Unfortunately the links point to the PNG file. I suspect a missing map directive. I posted a comment on same and hopefully it will be fixed soon.
In the meantime, enjoy the new release of Hadoop! (And thank the many contributors to the project this holiday season!)
