Description

HBASE-10141 is a good optimization, eliminating the need to scan already expired files (through TTL). However, I think if MIN_VERSIONS is set, it will not ensure that there will be at least that many versions since it bypasses the scan layer.

I think we can just do a simple check before the HBASE-10141 optimization to see whether MIN_VERSIONS is set for the table, and if so just do the regular old way of doing the scan in the compaction.
