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

             Summary: start-up needs to scale with the number of servers
                 Key: ACCUMULO-4043
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-4043
             Project: Accumulo
          Issue Type: Bug
          Components: scripts
    Affects Versions: 1.6.4
         Environment: very large production cluster
            Reporter: Eric Newton
             Fix For: 1.8.0


When starting a very large production cluster, the master gets running fast enough that it
loads the metadata table before all the tservers are registered and running. The result is
a very long balancing period after all servers started. The wait period for the tablet server
stabilization needs to scale somewhat with the number of tablet servers.
