Well, as its a new addition, support 0.98.4 as the first version doesn't seem
like that big of an issue - basically, "add these configs and roll your cluster
with the new hbase + phoenix".
And it would be nice to drop all the 0.98.3 specific code of out of the patch
(which creates its own RpcExecutor, reflection, etc). Not worth all the extra
work to make it work with the inheritance heirarchy

> With our current global secondary indexing solution, a batched Put of table
> data causes a RS to do a batch Put to other RSs. This has the potential to
> lead to a deadlock if all RS are overloaded and unable to process the pending
> batched Put. To prevent this, we should use a higher priority queue to submit
> these Puts so that they're always processed before other Puts. This will
> prevent the potential for a deadlock under high load. Note that this will
> likely require some HBase 0.98 code changes and would not be feasible to
> implement for HBase 0.94.
