Thanks for initiating the thread Arun.
Can we add YARN-1051 <https://issues.apache.org/jira/browse/YARN-1051> to
the list? We have most of the patches for the sub-JIRAs under review and
have committed a couple.

Subject: Thinking ahead to hadoop-2.6

Folks,
With hadoop-2.5 nearly done, it's time to start thinking ahead to
hadoop-2.6.
Currently, here is the Roadmap per the wiki:
• HADOOP
• Credential provider HADOOP-10607
• HDFS
• Heterogeneous storage (Phase 2) - Support APIs for using
storage tiers by the applications HDFS-5682
• Memory as storage tier HDFS-5851
• YARN
• Dynamic Resource Configuration YARN-291
• NodeManager Restart YARN-1336
• ResourceManager HA Phase 2 YARN-556
• Support for admin-specified labels in YARN YARN-796
• Support for automatic, shared cache for YARN application
artifacts YARN-1492
• Support NodeGroup layer topology on YARN YARN-18
• Support for Docker containers in YARN YARN-1964
• YARN service registry YARN-913
My suspicion is, as is normal, some will make the cut and some won't.
Please do add/subtract from the list as appropriate. Ideally, it would be
good to ship hadoop-2.6 in a 6-8 weeks (say, October) to keep up a cadence.
More importantly, as we discussed previously, we'd like hadoop-2.6 to be
the *last* Apache Hadoop 2.x release which support JDK6. I'll start a
discussion with other communities (HBase, Pig, Hive, Oozie etc.) and see
how they feel about this.
thanks,
Arun
