Re: [VOTE] Release hadoop-2.0.0-alpha
Siddharth Seth 2012-05-14, 21:14
Do we want to get MAPREDUCE-4067 in as well ? It affects folks who may be
writing their own AMs. Shouldn't affect MR clients though. I believe 2.0
alpha doesn't freeze the Yarn protocols for the 2.0 branch, so probably not
critical.

Thanks
