------------------------------

             Summary: HRegionServer#createRegionLoad() should reuse RegionLoad.Builder instance
                 Key: HBASE-11219
                 URL: https://issues.apache.org/jira/browse/HBASE-11219
             Project: HBase
          Issue Type: Improvement
            Reporter: Ted Yu
            Assignee: Ted Yu


As Andrew showed in the attachment to HBASE-11165, ClusterStatusProtos$RegionLoad$Builder
took 25MB heap space.

buildServerLoad() calls createRegionLoad() for each region on the region server.
One instance of ClusterStatusProtos$RegionLoad$Builder can be created outside the loop and
passed to createRegionLoad().

Thanks Andrew for the finding.
