>
> 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.
