> 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.
