Jerry He commented on HBASE-15055:
----------------------------------

To ask the question in a better way.
If it turns out to be a minor compaction, would the new logic (don't exclude 
big files because we want to take care of TTL expiration) still kick in?

> Major compaction is not triggered when both of TTL and 
> hbase.hstore.compaction.max.size are set
> -----------------------------------------------------------------------------------------------

> Some large files may be skipped by hbase.hstore.compaction.max.size in 
> candidate selection. It causes skipping of major compaction. So the TTL 
> expired records are still remained in the disks and keep consuming disks.
> To resolve this issue, I suggest that to skip large files only if there is no 
> TTL expired record.
