[jira] [Created] (PHOENIX-5720) Multiple scans on the same table region cause incorrect IndexTool counters

Kadir OZDEMIR created PHOENIX-5720:
--------------------------------------

             Summary: Multiple scans on the same table region cause incorrect IndexTool counters
                 Key: PHOENIX-5720
                 URL: https://issues.apache.org/jira/browse/PHOENIX-5720
             Project: Phoenix
          Issue Type: Improvement
    Affects Versions: 4.14.3, 5.0.0
            Reporter: Kadir OZDEMIR
            Assignee: Kadir OZDEMIR


IndexTool records its counters on an HBase table and uses table region name as the row key. When there are multiple scans on the same table region (i.e., when there are multiple MR mappers working on the same table region), these rows get overwritten and this leads to incorrect total counts.
