[jira] [Created] (HBASE-24465) Normalizer should consider region max file size when planning merges

Nick Dimiduk created HBASE-24465:
------------------------------------

             Summary: Normalizer should consider region max file size when planning merges
                 Key: HBASE-24465
                 URL: https://issues.apache.org/jira/browse/HBASE-24465
             Project: HBase
          Issue Type: Improvement
          Components: master
            Reporter: Nick Dimiduk


When the normalizer plans its actions, it does not consider {{hbase.hregion.max.filesize}}. This means it could get into a merge/split loop in collaboration with the region server: the normalizer sees two regions are smaller than the table average, it merges them. The resulting region is larger that this max file size, so the region server splits them. Repeat.
