Subject Re: Question on DFS Balancing
Date Wed, 05 Mar 2014 07:47:38 GMT
Thanks Harsh. The jira is fixed in version 2.1.0 whereas I am using Hadoop
0.20.2 (we are in a process of upgrading) is there a workaround for the
short term to balance the disk utilization? The patch in the Jira, if
applied to the version that I am using, will it break anything?

Thanks
Divye Sheth
