Review comment:
sendLocalClearRegionMessage() method is shared by all the 3 mesgs:
obtainWriteLockForClear, clearRegion, releaseWriteLockForClear. So it's better
to rename it to sendPRClearOperationMessage, or other generic name. It should
not be "LocalClear".

> Key: GEODE-7678
> URL: https://issues.apache.org/jira/browse/GEODE-7678
> Project: Geode
> Issue Type: Sub-task
> Components: regions
> Reporter: Nabarun Nag
> Priority: Major
> Labels: GeodeCommons
>
> Clear operations are successful and CacheListener.afterRegionClear(),
> CacheWriter.beforeRegionClear() are invoked.
>
> Acceptance :
> * DUnit tests validating the above behavior.
> * Test coverage to when a member departs in this scenario
> * Test coverage to when a member restarts in this scenario
> * Unit tests with complete code coverage for the newly written code.
