Hey Bobby,

 Thanks for getting this RC out.

 You might want to pull in YARN-137 and YARN-138 into this too.

at Yahoo!.  We just installed 0.23.3 on a 2000 node cluster and have only seen a few issues
(HDFS-3990 is the biggest of them).   I expect to do a 0.23.5 release in the coming weeks/months
as we find more issues running on large clusters.
