Work on HBASE-22952 started by Peter Somogyi.
---------------------------------------------
> HBCK2 replication command is incompatible with 2.0.x
> ----------------------------------------------------
>
> Key: HBASE-22952
> URL: https://issues.apache.org/jira/browse/HBASE-22952
> Project: HBase
> Issue Type: Bug
> Components: hbase-operator-tools
> Affects Versions: operator-1.0.0
> Reporter: Peter Somogyi
> Assignee: Peter Somogyi
> Priority: Critical
> Fix For: operator-1.0.0
>
>
> HBCK2 does not have a valid version check for `replication` command on 2.0
> releases.
> This command relies on ReplicationQueueStorage and ReplicationStorageFactory
> classes which were added in 2.1.0 so running HBCK2 replication on a 2.0
> cluster causes runtime error.
