In master when handling a split, the offline of parent and online of children is not done atomically
----------------------------------------------------------------------------------------------------

                 Key: HBASE-3284
                 URL: https://issues.apache.org/jira/browse/HBASE-3284
             Project: HBase
          Issue Type: Bug
          Components: master
    Affects Versions: 0.90.0
            Reporter: Jonathan Gray
             Fix For: 0.92.0


In AssignmentManager.handleSplitReport() we do:

{noformat}
    regionOffline(parent);
    regionOnline(a, hsi);
    regionOnline(b, hsi);
{noformat}

Within each of these, there is locking, but there is no locking around this entire operation.
 There should be.

This might be the cause of HBASE-3278
