             Summary: Balancer should check region plan source to avoid misplace region groups
                 Key: HBASE-25621
                 URL: https://issues.apache.org/jira/browse/HBASE-25621
             Project: HBase
          Issue Type: Improvement
          Components: Balancer
            Reporter: Xiaolin Ha
            Assignee: Xiaolin Ha


Currently, balancer generates all group plans firstly, and then execute overall plans. When there are table regions movement between groups but after the groups plans generating and before executing, balancer may misplace the region to the old group. But this is not serious problem, next balancer will fix it. 

If we add a check before executing balance plans, we can avoid the problem.
