[jira] [Created] (HBASE-16566) Add nonce support to TableBackupProcedure

Ted Yu created HBASE-16566:
------------------------------

             Summary: Add nonce support to TableBackupProcedure
                 Key: HBASE-16566
                 URL: https://issues.apache.org/jira/browse/HBASE-16566
             Project: HBase
          Issue Type: Improvement
            Reporter: Ted Yu


We should pass in nonce to avoid duplicate table backup RPC (the same RPC sent to server multiple times).

The duplicate table backup RPC may happen due to master failover.
If there is no nonce, same procedure may be executed more than once.
