> URL: https://issues.apache.org/jira/browse/HBASE-28401
> Project: HBase
> Issue Type: Sub-task
> Components: in-memory-compaction, regionserver
> Reporter: Duo Zhang
> Assignee: Duo Zhang
> Priority: Major
> Labels: pull-request-available
> Fix For: 2.6.0, 3.0.0-beta-2, 2.5.9

> Per the analysis in parent issue, we will always have an active segment in
> memstore even if it is empty, so if we do not call close on it, it will lead
> to a netty leak warning message.
> Although there is no real memory leak for this case, we'd better still fix it
> as it may hide other memory leak problem.
