> Reduce frequency of getDatanodeListForReport calls for metrics
> --------------------------------------------------------------
>
> Key: HDFS-17878
> URL: https://issues.apache.org/jira/browse/HDFS-17878
> Project: Hadoop HDFS
> Issue Type: Improvement
> Reporter: Felix N
> Assignee: Felix N
> Priority: Minor
> Labels: pull-request-available
>
> getDatanodeListForReport is called by a lot of metrics method while holding
> synchronized lock, interfering with more critical ops like datanodeReport
> while not having critical data (metrics). Best to reduce the frequency of
> calls to this method.
