Daniel Dai commented on PIG-2239:
---------------------------------

Let hadoop figure out its own dependencies should be the right way. Currently 
Pig is very cumbersome in finding hadoop jar and its dependencies. This issue 
will become more apparent once Pig support both hadoop 20 and 23. The only 
downside of this approach is we will rely on hadoop command line processor to 
process Pig command line, and possibly create backward compatibility issues. 

> Pig should use "bin/hadoop jar pig-withouthadoop.jar" in bin/pig instead of 
> forming java command itself
