Mahadev konar created AMBARI-15294: -------------------------------------- Summary: HBase RegionServer circular decommission Key: AMBARI-15294 URL: https://issues.apache.org/jira/browse/AMBARI-15294 Project: Ambari Issue Type: Bug Affects Versions: 2.2.1 Reporter: Mahadev konar
rovision a cluster with the attached blueprint with more than 2 hosts in the host_group_slave_1 host group. Put a few RegionServers to maintenance mode and try to decommission one of the RSs. It will try to find valid targets to move the data to, but it includes RSs in maintenance mode. In case of larger number of decommission like 20, it leads to circular data movements as RSs which are decommissioning will copy their data to other RSs which are also decommissioning. In the log you can see the selected targets and 80% of them is in maintenance mode. 15 nodes decommission 1 RS. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
