---------------------------------

             Summary: Multi-actions in hbase-client could fall in dead loop when region moves.
                 Key: HBASE-13896
                 URL: https://issues.apache.org/jira/browse/HBASE-13896
             Project: HBase
          Issue Type: Bug
          Components: Client
    Affects Versions: 0.98.13
            Reporter: Victor Xu
            Priority: Minor


The code in AsyncProcess.receiveGlobalFailure() use only one row to update region cache in
hbase-client. When we use HTable.put(List<Put>) api to write some data which are from
different regions and some of them are moved/balanced while writing, the client may fall into
a dead loop: multi-actions fails because some regions moved => update only one region cache(not
the wrong ones) => resubmit => failed again.
It only happens in 0.98 branch, and the master branch is ok.
The patch followed should update all cached region locations when multi-actions fails.
