> Currently, if store has one (major compacted) file, the only case when major compaction will be triggered for this file again - when locality is below threshold, defined by *hbase.hstore.min.locality.to.skip.major.compact* or TTL expired some cells. If file has locality greater than this threshold it will never be major compacted until Store's TTL kicks in. For CF with KEEP_DELETED_CELLS on, compaction must be enabled always (even for single file), regardless of locality, when deleted cells are expired (*hbase.hstore.time.to.purge.deletes*)
