-----------------------------------
Thanks for putting this up!
> DefaultMetricsSystemInitializer should be called during HMaster or
> HRegionServer creation

> Key: HBASE-28026
> URL: https://issues.apache.org/jira/browse/HBASE-28026
> Project: HBase
> Issue Type: Bug
> Components: metrics
> Reporter: Nihal Jain
> Assignee: Nihal Jain
> Priority: Major
>
> Concern is the jvm metrics somehow started populating with process name as IO
> instead of expected RegionServer/Master. See
> https://issues.apache.org/jira/browse/HBASE-27966 for RCA and a stop-gap fix.
> But this does not fix the problem, just hides it. We should be able to figure
> out why the metrics is getting initialized in BaseSourceImpl instead of
> during HMaster/RS process creation. We may need to refactor/move the code
> around to fix the same.
> See review comments of [https://github.com/apache/hbase/pull/5323] for more
> details.
