> 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.
