Subject [jira] [Commented] (HDFS-7116) Add a metric to expose the bandwidth of balancer
Date Sat, 22 Aug 2015 15:07:45 GMT

    [ https://issues.apache.org/jira/browse/HDFS-7116?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14708057#comment-14708057
] 

Tsz Wo Nicholas Sze commented on HDFS-7116:
-------------------------------------------

How about having "dfsadmin -getBalancerBandwidth <DATANODE_HOST:IPC_PORT>", which is
similar to "dfsadmin -getDatanodeInfo"?

Or how about extending the "hdfs getconf" command to support getting conf from datanode?

> Now reading logs is the only way to check how the balancer bandwidth is set. It would
be useful for administrators if they can get the value of the same. This jira to discuss &
implement the way to access the balancer bandwidth value of the datanode.
