------------------------------------

             Summary: Do not reset the mvcc for bulk loaded mob reference cells in reading
                 Key: HBASE-13836
                 URL: https://issues.apache.org/jira/browse/HBASE-13836
             Project: HBase
          Issue Type: Sub-task
          Components: mob
    Affects Versions: hbase-11339
            Reporter: Jingcheng Du
            Assignee: Jingcheng Du
             Fix For: hbase-11339


Now in scanner, the cells mvcc of the bulk loaded files are reset by the seqId parsed from
the file name. We need to skip this if the hfiles are bulkloaded in mob compactions.
In mob compaction, the bulk loaded ref cell might not be the latest cell among the ones that
have the same row key. In reading, the mvcc is reset by the largest one, it will cover the
real latest ref cell. We have to skip the resetting in this case.
The solution is we add a new field to fileinfo, when this field is set as true, we skip the
resetting.
