Verifying Migration

After copying data to the new tables, verify that the migration is complete and successful. In increasing order of complexity:
  1. Verify that the destination table exists. From the HBase shell, use the list command, or use the ls /user/john/foo command from a Linux prompt:
    hbase(main):006:0> list '/user/john/foo'
    1 row(s) in 0.0770 seconds
  2. Check the number of rows in the source table against the destination table with the count command:
    hbase(main):005:0> count '/user/john/foo/mytable01'
    30 row(s) in 0.1240 seconds
  3. Hash each table, then compare the hashes.
