> Running some tests, I set hbase.client.scanner.caching=1000. Dataset has
> large cells. I kept OOME'ing.
> Serverside, we should measure how much we've accumulated and return to the
> client whatever we've gathered once we pass out a certain size threshold
> rather than keep accumulating till we OOME.
