There are couple of differences:
* JobContext is a hadoop concept, UDFContext is a Pig concept
* JobContext is per Map-reduce job, UDFContext is per Pig store
Usually you store some per store settings inside UDFContext, and retrieve it
later.
Properties p = UDFContext.getUDFContext().getUDFProperties(this.getClass());
p.setProperty("someproperty", value);
You do not use JobContext directly in Pig.
