[jira] [Created] (HBASE-15665) Support using different StoreFileComparators for different CompactionPolicies

Duo Zhang created HBASE-15665:
---------------------------------

             Summary: Support using different StoreFileComparators for different CompactionPolicies
                 Key: HBASE-15665
                 URL: https://issues.apache.org/jira/browse/HBASE-15665
             Project: HBase
          Issue Type: Sub-task
            Reporter: Duo Zhang
            Assignee: Duo Zhang


Now for DateTieredCompactionPolicy, if we output multiple files when compaction, we will use the same max sequence id for all the output files(see HBASE-15389 for more details). So we need to sort the store files by timestamp if they have the same max sequence id which is different from the original store file comparator.
