Re: [VOTE] Release Apache Hadoop 2.2.0
Vinod Kumar Vavilapalli 2013-10-13, 17:37

Ran through my usual check-list.
 - Signatures and message digests all good.
 - The top level full LICENSE, NOTICE and README files look fine.
 - CHANGES.txt for common, hdfs, yarn and mapped are located as in before releases.
 - Able to build the tars out of the source tar ball.

Testing: Built from the source tarball. All testing on single node, non-secure setup - with separate installation directories for each sub-project.
Successfully started mapred history server.
Started HDFS daemons successfully.
Successfully started YARN daemons - ResourceManager and NodeManager
Ran YARN's distributed shell example.
Ran sleep, wordcount, pi, random writer, sort, grep and they all pass just fine.
App/Job listing, killing jobs all work well from the CLI.
Did basic YARN/MAPRED UI browsing, all seems well.
I am surprised no one else mentioned this. Besides symlinks, there is one more incompatible change that I hit (as I expected). We should call out the following incompatible change in the release notes.
    YARN-1229. Define constraints on Auxiliary Service names. Change
    ShuffleHandler service name from mapreduce.shuffle to
    mapreduce_shuffle (Xuan Gong via sseth)
With that, here's my +1 for the RC. Ship it!
Thanks,
+Vinod
