Description
Currently we take exclusive lock on hbase:backup table in backup / restore procedures.
There is only one backup or restore operation which can run at given time.
We should consider using shared lock on hbase:backup table in the procedures so that concurrent backup / restore operations can proceed.
The concurrency is useful when table sets don't overlap.
We may devise other mechanism(s) when there is overlap among the table sets.
