      <!-- markdown -->
      Users who have previously made use of prefix tree encoding can now check that their existing HFiles no longer contain data that uses it with an additional preupgrade check command.

      ```
      hbase pre-upgrade validate-hfile
      ```

      Please see the "HFile Content validation" section of the ref guide's coverage of the pre-upgrade validator tool for usage details.

      Description

      HBASE-20592 adds a tool to check column families on the cluster do not have PREFIX_TREE encoding.

      Since it is possible that DataBlockEncoding was already changed but HFiles are not rewritten yet we would need a tool that can verify the content of hfiles in the cluster.
