Subject Re: [VOTE] Release Apache Hadoop 2.1.0-beta
Date Wed, 26 Jun 2013 09:55:09 GMT
+1 only for HDFS and common.

I compiled using source, now everything I tested is fine.

I configured QJM HA, enabled short circuit read, ran a MRv1 job;


note: my testing cluster using HDFS-2.1.0-beta and common-2.1.0-beta, but
MR is 1.1.2.( I did some change)
