             Summary: Monitor gets slow with lots of migrations
                 Key: ACCUMULO-4625
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-4625
             Project: Accumulo
          Issue Type: Bug
          Components: master, monitor
    Affects Versions: 1.6.6
            Reporter: Michael Wall


An anecdotal ticket until I can dig further.  The monitor gets really slow when there is a
large number of migrations that need to happen.  For example, create a table.  Then add 1000
splits.  All tablets are assigned to one tserver until they are migrated.  May even queue
up needed migrations from other tables behind those 1000 migrations.
