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

             Summary: Allow tserver to reject migration
                 Key: ACCUMULO-4728
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-4728
             Project: Accumulo
          Issue Type: Improvement
          Components: tserver
            Reporter: Charles Williams
            Assignee: Charles Williams
            Priority: Minor


An otherwise well functioning tserver may fail to load a tablet indefinitely without the master
re-assigning the tablet to another tserver. In some cases the tserver may be miss configured
in some way that prevents loading a set of specific tablets from a specific set of tables.


If the tserver could respond to the master with a failure to load a tablet and abort the master
could then re-assign the tablet somewhere else. In some instances this could prevent an outage.
