Seems only this issue has been finished. https://issues.apache.org/jira/browse/HBASE-4605
Which brought in these classes, but the later approach on adding shell support had been resolved as incomplete. https://issues.apache.org/jira/browse/HBASE-4879 So I guess there is no actual use in HBase yet. Do you still want to finish this feature? Thanks.
