> 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.
