Qilin Cao updated HBASE-19521:
------------------------------
Description: 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. (was: When
