Ted Yu commented on HBASE-16566: -------------------------------- Looking at existing test in TestCreateTableProcedure#testCreateTwiceWithSameNonce : {code} ProcedureTestingUtility.waitProcedure(procExec, procId1); {code} Backing up a small table would take non-trivial time. I would skip adding test for this one. > 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 > Assignee: Ted Yu > Labels: backup > Attachments: 16566.v2.txt > > > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
