Jerry He created HBASE-19021: -------------------------------- Summary: Restore a few important missing logics for balancer in 2.0 Key: HBASE-19021 URL: https://issues.apache.org/jira/browse/HBASE-19021 Project: HBase Issue Type: Bug Reporter: Jerry He Assignee: Jerry He Priority: Critical
After looking at the code, and some testing, I see the following things are missing for balancer to work properly after AMv2. # hbase.master.loadbalance.bytable is not respected. It is always 'bytable'. Previous default is cluster wide, not by table. # Servers with no assignments is not added for balance consideration. # Crashed server is not removed from the in-memory server map in RegionStates, which affects balance. # Draining marker is not respected when balance. Also try to re-enable {{TestRegionRebalancing}}, which has a {{testRebalanceOnRegionServerNumberChange}} -- This message was sent by Atlassian JIRA (v6.4.14#64029)
