> Key: HBASE-7309
> URL: https://issues.apache.org/jira/browse/HBASE-7309
> Project: HBase
> Issue Type: Bug
> Components: metrics, regionserver
> Affects Versions: 0.92.2, 0.94.3
> Reporter: Adrian Muraru
> Priority: Critical
> Attachments: HBASE-7309_v1.patch, HBASE-7309_v2.patch
>
>
> While investigating HBASE-7205 by repeatedly enabling and disabling one table
> having 100 regions I noticed that closed HRegion objects are kept forever in
> memory.
> The memory analyzer tool indicates a reference to HRegion object in metrics
> refresh-task ({{MetricsRegionWrapperImpl.HRegionMetricsWrapperRunnable}})
> that prevents the HRegion object to be collected.
