Subject [jira] [Commented] (HDFS-7116) Add a metric to expose the bandwidth of balancer
Date Fri, 21 Aug 2015 09:57:45 GMT

    [ https://issues.apache.org/jira/browse/HDFS-7116?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14706489#comment-14706489

Vinayakumar B commented on HDFS-7116:
-------------------------------------

bq. 1. Would you remove the sentence starts with "The new value is not persistent ... "? If
we add the metric, the new value does persist on the DataNodeMetrics.
IMO, exposing via metric is not same as persisting. It just shows out the current value. Here
not actually meant, new value is only till lifetime of the datanode. On restart it will be
reset. so i feel still NOTE is valid. May be the sentence related to exposing can be added
before the note. To make it clear.

> 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.
