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

 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
