> 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
> Priority: Major
>
> 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.
