--------------------------------------------------------------------
Let's see how many tests this breaks. If the change in behavior breaks too
many, I will add explicit flag to distinguish refresh vs shutdown and read that
in ensure... and replace best-effort stuff with an atomic or smth like that.

> HRegionServer rssStub handling is incorrect and inconsistent

> Key: HBASE-22432
> URL: https://issues.apache.org/jira/browse/HBASE-22432
> Project: HBase
> Issue Type: Bug
> Affects Versions: 3.0.0
> Reporter: Sergey Shelukhin
> Assignee: Sergey Shelukhin
> Priority: Critical
>
> Some methods refresh stub on null, some assume (incorrectly) server is
> shutting down.
> Most methods reset stub to null on error, and also now we do it when ZK
> changes.
> One of the latter can cause server reports to not be sent until one of the
> former methods (e.g. reporting procedure completion) executes and happens to
> restore the stub for them.
> Also, reset on error is done sometimes with and sometimes without a check.
