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

             Summary: Stochastic load balancer assigns replica regions to the same RS
                 Key: HBASE-18946
                 URL: https://issues.apache.org/jira/browse/HBASE-18946
             Project: HBase
          Issue Type: Bug
    Affects Versions: 2.0.0-alpha-3
            Reporter: ramkrishna.s.vasudevan
            Assignee: ramkrishna.s.vasudevan
             Fix For: 2.0.0-beta-1


Trying out region replica and its assignment I can see that some times the default LB Stocahstic
load balancer assigns replica regions to the same RS. This happens when we have 3 RS checked
in and we have a table with 3 replicas. When a RS goes down then the replicas being assigned
to same RS is acceptable but the case when we have enough RS to assign this behaviour is undesirable
and does not solve the purpose of replicas.
