Description

HBASE-18099 was only integrated to branch-1 and above in consideration of backward compatibility.

This issue is to backport the fix to branch-1.3 and branch-1.2.
Quoting Gary's suggestion from the tail of HBASE-18099 :

Sure, don't add the method to Region, just to HRegion, check for an instance of HRegion in FlushSnapshotSubprocedure and cast the instance before calling the method.
