> Key: HBASE-25767
> URL: https://issues.apache.org/jira/browse/HBASE-25767
> Project: HBase
> Issue Type: Improvement
> Components: Balancer, Performance
> Reporter: Duo Zhang
> Assignee: Duo Zhang
> Priority: Major
> Fix For: 3.0.0-alpha-1, 2.5.0, 2.4.3, 2.3.6
>
>
> Similar to HBASE-25759, it is just used to test whether we should skip
> calculation, but in production masterServices will never be null.
> ==========
> Update, change the title of this issue for removing
> CandidateGenerator.getRandomIterationOrder as it is too slow which causes the
> CandidateGenerator.getRandomIterationOrder to fail when we remove the
> masterServices field in LocalityBasedCandidateGenerator. As this is the most
> important change in this issue so change the title of this issue.
