[jira] [Resolved] (HBASE-18613) Race condition between master restart and test code when restoring distributed cluster after integration test

     [ https://issues.apache.org/jira/browse/HBASE-18613?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Josh Elser resolved HBASE-18613.
--------------------------------
    Resolution: Invalid

Jumped the gun on this one. That warning wasn't actually fatal. The test had failed due to some exceptions in the action a bit earlier in the log.

> This is when the IntegrationTest harness is resetting the state of the distributed cluster. When dealing with "slow" nodes, the restart of the previously active master could be delayed which cause the test code to see a ConnectionClosingException (wrapped in a ServiceException).
> I think we want to just consume this Exception, same as MasterNotRunningException and ZooKeeperConnectionException, in {{DistributedHBaseCluster#waitForActiveAndReadyMaster(long)}}.
