[jira] [Created] (HBASE-24643) Replace Cluster#primariesOfRegionsPerServer from int array to treemap

Huaxiang Sun created HBASE-24643:
------------------------------------

             Summary: Replace Cluster#primariesOfRegionsPerServer from int array to treemap
                 Key: HBASE-24643
                 URL: https://issues.apache.org/jira/browse/HBASE-24643
             Project: HBase
          Issue Type: Improvement
          Components: Balancer
    Affects Versions: 2.3.0
            Reporter: Huaxiang Sun
            Assignee: Huaxiang Sun


Currently, primariesOfRegionsPerServer is an int array, moveRegion does heavy work by searching the array (linearly) and insert/remove an element requires allocating/copying the whole array.
