> 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.
