             Summary: Expose max refCount among all compacted store files of a region
                 Key: HBASE-23349
                 URL: https://issues.apache.org/jira/browse/HBASE-23349
             Project: HBase
          Issue Type: Task
    Affects Versions: 3.0.0, 2.3.0, 1.6.0
            Reporter: Viraj Jasani
            Assignee: Viraj Jasani


We should expose a region level metric that represents max refCount among refCounts of all compacted store files under the region. For successful archival of compacted store files, it is important for this metric count to be 0 eventually if not immediately. If it is >0 for a considerably high amount of time, it indicates some issue i.e. reader refCount leak on some compacted store files and in such case, archival would not be successful.
