             Summary: Potential data loss when MOB compaction fails
                 Key: HBASE-22075
                 URL: https://issues.apache.org/jira/browse/HBASE-22075
             Project: HBase
          Issue Type: Bug
            Reporter: Vladimir Rodionov
            Assignee: Vladimir Rodionov


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.
