> 1. HiveCommands.txt : command script to setup schema for query under consideration.
> 2. sourceData1.txt and sourceData2.txt : required for above command script.

> NOTE: you will need to update path to sourceData1.txt and sourceData2.txt in the HiveCommands.txt
to suit your environment.

> It is worthwhile to note that the same query executes successfully on Hive 0.7.
