> during the STRIPE compaction,
> deletes(tombstones) are being dropped in 2 cases.
> 1. Compaction including L0 (includeL0 == true)
> 2. L0 has no files (canDropDeletesWithoutL0 == true)
> To drop delete marker and keep the consistency during compaction,
> All of HFiles in the stripe has to be selected, just like major compaction.
> otherwise, after the compaction only delete markers would be gone,
> and deleted cells (which is in the not-selected HFiles) are going to be alive
> again.
> In my cluster, there was no file on L0(canDropDeletesWithoutL0==true) and not
> all files are selected for compaction, so some of deleted rows have come back
> alive and appears when i get or scan after compactions.
> I made a patch about it.
> it checks if all files are selected before we set the majorRange of
> compaction request .
