Elliott Clark updated HBASE-8283:
---------------------------------

    Attachment: HBASE-8283-0.patch

Here's the 0.94 version. It's a pretty drastic change in behavior to be putting into 0.94 so I'm undecided on if this should go in.

It basically fixes bulk import workloads, but it *could* drastically change the amount of IO needed.

Thoughts?
