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.

 With hadoop-2.5 nearly done, it's time to start thinking ahead to

 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.
