      Description

      When I use 

      hbase org.apache.hadoop.hbase.snapshot.ExportSnapshot -snapshot "wh_scan_issue_monitor_on_snap_1" -copy-from hdfs://xxxx:8020/hbase  -copy-to hdfs://xxx:8020/hbase
      

      to copy snapshot from hbase2.0.0 to hbase 1.2.0 and then use

      clone_snapshot 'wh_scan_issue_monitor_on_snap_1',"wh_scan_issue_monitor_table"

      to restore the table;

      There are no errors on client and hbase master.

      but I can not scan any data in this new table.

      So when I search the log in regionserver which that region running on .I find the below error log
