             Summary: retrying to close a region incorrectly resets its RIT age metric
                 Key: HBASE-21757
                 URL: https://issues.apache.org/jira/browse/HBASE-21757
             Project: HBase
          Issue Type: Bug
    Affects Versions: 3.0.0
            Reporter: Sergey Shelukhin


We have a region stuck in RIT forever due to some other bug that I will file later.
Every 10 minutes it does the typical split-brain retry; I noticed that this retry resets the region's RIT age, so the "oldest RIT" metric never becomes larger than ~10mins even though the region has been stuck for days.
