Re: Heads up: next hadoop-2 release
Robert Evans 2012-08-31, 17:26
Yes, I hope to branch and make the RC Tuesday of next week.  There was a
flurry of new issues that came up recently.

I am now waiting on

YARN-60
YARN-66
MAPREDUCE-4612
MAPREDUCE-4611

But I would like to also have in

HDFS-3852
MAPREDUCE-4604
HADOOP-8727
