Subject [jira] [Updated] (HDFS-9461) DiskBalancer: Add Report Command
Date Tue, 24 Nov 2015 22:43:10 GMT

     [ https://issues.apache.org/jira/browse/HDFS-9461?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

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.
