----------------------------------------------

I think Lars is referring to HBASE-4721 by Prakash. Yes, worth making sure it plays well with that -- though I suspect it should work out just fine.

> Currently, HBase deletes the out of TTL store files after major compaction. We can change the sequence to delete the out of TTL store files before selecting store files for compactions. 
> In this way, HBase can keep deleting the old invalid store files without major compaction, and also prevent from unnecessary major compactions since the out of TTL store files will be deleted before the compaction selection.
