> Better to exclude decommissioned nodes for namenode NodeUsage JMX
> -----------------------------------------------------------------
>
> Key: HDFS-8670
> URL: https://issues.apache.org/jira/browse/HDFS-8670
> Project: Hadoop HDFS
> Issue Type: Bug
> Reporter: Ming Ma
> Assignee: J.Andreina
> Attachments: HDFS-8670.1.patch
>
>
> The namenode NodeUsage JMX has Max, Median, Min and Standard Deviation of
> DataNodes usage, it currently includes decommissioned nodes for the
> calculation. However, given balancer doesn't work on decommissioned nodes and
> sometimes we could have nodes stay in decommissioned states for a long time;
> it might be better to exclude decommissioned nodes for the metrics
> calculation.
