huaxiang sun commented on HBASE-18946: -------------------------------------- Do we need to apply the same collection logic to EnableTableProcedure (to address the TODO in the comment)? Otherwise, +1. > 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 > > Attachments: HBASE-18946.patch, HBASE-18946.patch, > TestRegionReplicasWithRestartScenarios.java > > > 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. > [~huaxiang] and [~enis]. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
