---------------------------------------

bq. Store is exposed to CPs and this method make no sense for CPs
Yeah, that makes sense, I'll remove it from the Store interface.

bq. may be even the Region level method need not be exposed if already the
closeRegionOperation(Operation) was not exposed earlier.
I think the closeRegionOperation(Operation) makes sense at the Region level. In
fact, I would argue that starRegionOperation() and closeRegionOperation()
without arguments don't make much sense. The Operation enum is defined in the
Region interface, it should expose a method to start and close specific
operations.

> Failing to take snapshot due to FileNotFoundException
> * FlushSnapshotSubprocedure.RegionSnapshotTask takes a region level read
> lock
> * Call to HRegion#addRegionToSnapshot.
> * Call to SnapshotManifest#addRegion. This gets the current list of store
> files.
> * RACE → File is marked as compacted away and HFileArchiver moves the
> file to archive under store level lock.
> * SnapshotManifest#addRegion visits the stale list of store files one by
> one. It does a file.getStatus() call to get length of each file. Since the
> file object still points to the original file, file.getStatus() fails with
> FileNotFoundException.
