> 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.
