Date Tue, 18 Mar 2014 22:24:42 GMT
John Vines created ACCUMULO-2496:
------------------------------------

             Summary: Monitor reporting up tserver as down
                 Key: ACCUMULO-2496
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-2496
             Project: Accumulo
          Issue Type: Bug
    Affects Versions: 1.5.1
            Reporter: John Vines


While attempting to reproduce ACCUMULO-2361, I got into a state where the monitor was reporting
my one tserver offline, but the tserver was still running. Lock was still in place the only
issue the monitor seems to have had with it is {code} Error processing table state for store
