[jira] [Created] (HBASE-16579) Concurrent backup / restore support

Ted Yu created HBASE-16579:
------------------------------

             Summary: Concurrent backup / restore support
                 Key: HBASE-16579
                 URL: https://issues.apache.org/jira/browse/HBASE-16579
             Project: HBase
          Issue Type: Improvement
            Reporter: Ted Yu


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.
