-----------------------------------
> 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
> Priority: Major
> Fix For: 3.0.0-alpha-1, 2.5.0, 2.3.5, 2.4.3
>
>
> 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.
