I've tried running the bin/hadoop balance command since I recently added a new node to the Hadoop cluster. I noticed the following output in the beginning:
08/12/03 10:26:35 INFO balancer.Balancer: Will move 10 GBbytes in this iteration Dec 3, 2008 10:26:35 AM 0 0 KB 2.67 GB 10 GB 08/12/03 10:26:36 WARN balancer.Balancer: Error moving block -6653850537520285828 from 10.30.2.31:50010 to 10.30.2.23:50010 through 10.30.2.31:50010: block move is failed However, subsequent iterations have succeeded. Is this harmless or is there a possibility that data was corrupted during the re-balancing attempt? Thanks, Ryan
