Review comment:
It should not be since in ConnectionFactory we have that check-in place.
[link](https://github.com/apache/phoenix/blob/4.x/phoenix-core/src/main/java/org/apache/phoenix/util/ServerUtil.java#L362).
Also on hbase side we throw IAE in case connection is null

Let me know if you think otherwise.

Review comment:
@tkhurana I also thought of doing exactly this while making the above
change. But while checking the underlying hbase implementations, when we pass
`pool = null` this
[getDefaultExecutor](https://github.com/apache/hbase/blob/branch-1.4/hbase-client/src/main/java/org/apache/hadoop/hbase/client/HTable.java#L213)
is called
[here](https://github.com/apache/hbase/blob/branch-1.4/hbase-client/src/main/java/org/apache/hadoop/hbase/client/HTable.java#L320)
to create the ThreadPool, but in the scenario when no pool object is passed
like in our case on [line
320](https://github.com/apache/phoenix/pull/1328/files#diff-28b6df839a384471211d620c7845ea2a40c8ef67e35966a07122bb4f8938086dR320)
the underlying ThreadPool creation is different
[Link](https://github.com/apache/phoenix/pull/1328/files#diff-28b6df839a384471211d620c7845ea2a40c8ef67e35966a07122bb4f8938086dR320)
and
[getBatchPool](https://github.com/apache/hbase/blob/branch-1.4/hbase-client/src/main/java/org/apache/hadoop/hbase/client/C
onnectionManager.java#L827) is called. That's why I did merge those two
function calls.
Please let me know if I am missing anything and you still think we should
make the above refactor. Thanks
