> 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.
