[jira] [Created] (HBASE-13836) Do not reset the mvcc for bulk
loaded mob reference cells in reading
Jingcheng Du created HBASE-13836:
------------------------------------
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.
