> While debugging something else, I've noticed that HBASE-12422 changed it so that new HTable(Configuration, TableName) is not using managed connections anymore. 
> I thought the plan was to keep new HTable(Conf, TableName) to still use managed connections, but allow the new APIs to have un-managed connections. With HBASE-12422, there is a big compatibility change for used of the HTable interface that suddenly they will be launching connections per HTable instance which is a behavioral change and expensive (with all the meta cache, zk threads, thread pool, etc). I fear that this will catch unsuspecting users by surprise, that is why I think we should revert back to the deprecated behavior for 1.0. For master we do not need to make the change, but document it.
