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

             Summary: splitting a tablet results in bogus warnings
                 Key: ACCUMULO-774
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-774
             Project: Accumulo
          Issue Type: Bug
          Components: master, tserver
            Reporter: Eric Newton
            Assignee: Eric Newton
            Priority: Minor


Asking a tablet server to split a tablet can result in an unbalanced load.  When the balancer
runs, it returns a plan to move the tablets. The next run of the state machine will send unload
messages to tablet servers.  This, in turn, will result in waking up the master to re-run
the state machine.  In this way, the master ends up queuing many requests to unload a tablet.
 Eventually the tablet server will unload the tablet and then complain about being asked to
unload a tablet that is no longer loaded.
