Subject Re: MR-279 branch: Problem opening files on the namenode web console (need to pick patches from trunk to resolve)
Date Sat, 09 Jul 2011 02:00:42 GMT
HI Amhed,
 We are still working to start using trunk hdfs and trunk common for
MR-279 (mapreduce). I think we are almost there and should be ready
next week. For now we can probably skip fixing it since we are anyway
going to move to trunk hdfs. Does that seem reasonable?

thanks
mahadev
