Thanks Andrew Wang for driving this effort and also thanks to all others
who helped in this release. Kudos!!!

I tested this RC by building it from source. I met with couple of issues
(not blocker) HADOOP-15116 and YARN-7650. This could be tracked separately.

   - Ran many MR apps and verified both new YARN UI and old RM UI.
   - Tested below feature sanity and got results as per the behavior
      - Application priority (verified CLI/REST/UI etc)
      - Application timeout
      - Intra Queue preemption with priority based
      - Inter Queue preemption
   - Tested basic NodeLabel scenarios.
      - Added couple of labels to few of nodes and behavior is coming
      - Verified old UI  and new YARN UI for labels.
      - Submitted apps to labelled cluster and it works fine.
      - Also performed few cli commands related to nodelabel.
   - Test basic HA cases and seems correct. However I got one issue.
   Raised HADOOP-15116 as its not a blocker.
   - Also tested new YARN UI . All pages are getting loaded correctly.
   (User must enable CORS to access NodeManager pages)
   - *Performance test*: I ran a tight loop perf test on CS
   Results are a bit off w.r.t 2.8  (~5% less). I will open a ticket and
   investigate by doing more tests to see if its to be addressed or not.
