> From discussions in HBASE-7667, and in person.
> Files cannot be "just moved" to new regions because of snapshot reliance on that not happening (correct me if I'm wrong).
> However, obviously we don't need compaction after split if we have files with specific ranges, so we could handle this somehow.
> On the other hand, if you have 6 fixed stripes, and split into 3 and 3, you'd want to go back to 6 stripes, so when you do compaction in one of the 3 you will want special handling to do it.
