Pradeep Kamath updated PIG-1323:
--------------------------------

    Attachment: PIG-1323.patch

Attached patch addresses the issue in the description by setting state in the Configuration depending on where in PigInputFormat the LoadFunc.setLocation() method is called. No tests are includes since testing this in a unit test framework is not feasible - I have manually tested this.

> Loaders which interact with external systems like a metadata server may need to know if the LoadFunc.setLocation call happens from the frontend (on the client machine) or in the backend (on each map task). The Configuration in the Job argument to setLocation() can contain this information.
