Re: Logistics for releasing 2.4
I just committed the addendum patch for HADOOP-9652 which should resolve
the performance issue.

Speaking of critical issues to fix for 2.3, I do wonder what to do with
all the Blocker/Criticals targeted for 2.4 (the old branch-2 HEAD
release) which apparently is now going to be 2.3 (the new branch-2 HEAD
release).  We should either get these resolved before the 2.3 release or
decide which ones aren't really blockers or that critical for 2.3 and
target them for a future release (e.g.: 2.4). According to my
calculations, there's currently 24 JIRAs that need to be scrubbed
accordingly.

https://issues.apache.org/jira/issues/?jql=project%20in%20%28hadoop%2C%20hdfs%2C%20mapreduce%2C%20yarn%29%20and%20resolution%20%3D%20Unresolved%20and%20priority%20in%20%28Blocker%2C%20Critical%29%20and%20%22Target%20Version%2Fs%22%20in%20%28%222.3.0%22%2C%20%222.4.0%22%29
