Subject Re: [VOTE] 0.23.4 release
Date Sat, 29 Sep 2012 23:00:44 GMT
Hi Robert,

Source artifacts are missing. Could you please upload those as a
separate tarball like the last time?

+1 from me (non-binding) for the binaries otherwise.

Verified the signature.

➜  gpg --verify hadoop-0.23.4.tar.gz.asc hadoop-0.23.4.tar.gz
gpg: Good signature from "Robert Joseph Evans (Bobby) <bobby[at]apache[dot]org>"

Ran a single machine cluster and ran a couple of MR jobs and the
distributed shell YARN app (needed extra configuring, check
https://issues.apache.org/jira/browse/MAPREDUCE-3869 for your next
release, if you perhaps want to make the experience better?). Seems to
work alright.

➜  bin/yarn jar
share/hadoop/mapreduce/hadoop-mapreduce-examples-0.23.4.jar pi
-Dmapreduce.framework.name=yarn 10 10
Estimated value of Pi is 3.20000000000000000000

upgrading of a 1.0 cluster with append/sync enabled should now work (HDFS-3731).  There are
no known blockers against this release, there are only two critical issues.

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.
