stack commented on HBASE-12835:
-------------------------------
I see your point [~enis] Over on the issue, thought concern was about closing
and that had been dealt with. Lets be conservative and move this one back to
managed connections (Might explain the horrors [~jurmous] struggled with in
TestHBaseFsck... where he did a bunch of work to shut down number of running
connections?)
> HBASE-12422 changed new HTable(Configuration) to not use managed Connections
> anymore

> 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.
> [~sduskis], [[email protected]], [~ndimiduk] what do you guys think?
