Subject Re: Merge Namenode HA feature to 0.23
Date Sun, 04 Mar 2012 17:43:19 GMT
Hey Suresh,

+1  Sounds great. Thanks for volunteering!

You'll probably want to merge HDFS-1580,  HDFS-1765, HDFS-2158,
HDFS-2188, HDFS-2334, HDFS-2476, HDFS-2477, and HDFS-2495 to branch-23
first as these conflict and the patch will contain a bunch of non-HA
stuff.

Thanks,
Eli
