> Key: HBASE-24039
> URL: https://issues.apache.org/jira/browse/HBASE-24039
> Project: HBase
> Issue Type: Improvement
> Components: hbck2, Operability
> Reporter: Richard Antal

>
> Each HBase version is shipped with a specific version of HBCK2 therefore we can check the HBCK2 version and decide if the given command is supported in that version or not.
> It is not that easy to decide if the command is supported or not when dealing with back-ported features.
> It the conclusion of this I would recommend using feature negotiation to check what commands are supported on the server side instead of comparing versions.
