This looks to me that we end up bulk-loading the MOB file that we created, not
the ref file? It's not clear to me what this is supposed to be doing.

This are artifacts of some code cleaning/modifications. The fileName argument
is not used at all in *bulkloadRefFile* method, but only bulkloadDir, where ref
file is located.

> When MOB compaction fails during last step (bulk load of a newly created
> reference file) there is a high chance of a data loss due to partially loaded
> reference file, cells of which refer to (now) non-existent MOB file. The
> newly created MOB file is deleted automatically in case of a MOB compaction
> failure, but some cells with the references to this file might be loaded to
> HBase.
