    Description

      org.apache.hadoop.hbase.UnknownScannerException: org.apache.hadoop.hbase.UnknownScannerException: Unknown scanner '644116'. This can happen due to any of the following reasons: a) Scanner id given is wrong, b) Scanner lease expired because of long wait between consecutive client checkins, c) Server may be closing down, d) RegionServer restart during upgrade.
      If the issue is due to reason (b), a possible fix would be increasing the value of'hbase.client.scanner.timeout.period' configuration.
