------------------------------
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.
