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

             Summary: 
TestStochasticLoadBalancerRegionReplicaLargeCluster.testRegionReplicasOnLargeCluster
 is flaky  
                 Key: HBASE-27054
                 URL: https://issues.apache.org/jira/browse/HBASE-27054
             Project: HBase
          Issue Type: Test
          Components: test
    Affects Versions: 2.5.0
            Reporter: Andrew Kyle Purtell
             Fix For: 2.5.0, 3.0.0-alpha-3


TestStochasticLoadBalancerRegionReplicaLargeCluster.testRegionReplicasOnLargeCluster
  . Looks like we can be off by one on either side of an expected value.

Any idea what is going on here [~dmanning]?
