Using Parlour with custom sql query execution before Sqoop export/import...

....
That is not entirely correct. Sqoop and SqoopExecution are different in the types they return. With regards to this method, it is private hence can't be directly accessed by SqoopExecution. We shouldn't make it public. We could make it package private and let SqoopExecution reuse it but personally I wouldn't do that for something this small. Thoughts?
