This PR proposes to support Hadoop 2.6+ for volume rebalancing
Since HDFS-6482, HDFS use the two-level directory structure for block storing, that is
{subdir0 ~ subdir255} / {subdir0 ~ subdir255}, so we can move the same subdir between two volumes.How was this patch tested?
This script has been used in product environment for volume rebalancing, and has a good performance.
