Xiaobing Zhou updated HDFS-9461:
--------------------------------
Description:
It's quite helpful to do:
1) report node information for the top X of DataNodes that will benefit from
running disk balancer
2) report volume level information for any specific DataNode.
This is done by:
1) reading the cluster info, sorting the DiskbalancerNodes by their
NodeDataDensity and printing out their corresponding information.
2) reading the cluster info, and print out volume level information for that
DataNode requested.
