> When HBase master configuration is not set hfile.format.version to 3, and
> user already run compact mob, this operation will cause compactor write V2
> ref hfile, the result is that user can not scan the correct cell value since
> the mob cell ref tags are not written. So it is necessary to check the hfile
> version before to run mob compaction.
