Re: [VOTE] Release Apache Hadoop 2.2.0

+1 for the release.

I have deployed a multinode cluster and extensively tested MR speculative 
execution, YARN CLI and YARN distributed shell. There were couple of issues I 
encountered while testing MAPREDUCE-5533, YARN-1168, YARN-1167, YARN-1157, 
YARN-1131, YARN-1118, YARN-1117 and all of them have been fixed.

Thanks,
Tassapol

 Summary: Speculative execution does not function for reduce

  Issue Type: Bug
  Components: applicationmaster
Reporter: Tassapol Athiapinya
 Fix For: 2.1.1-beta


We have sort job where reduce attempt does not send heartbeat in timely manner 
to application master. The AM should kick off another attempt to let job 
succeeds. What we find is the job fails and there is no speculation happening.
