      Description

      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.
