-Re: How Pig generates DAG

In the Pig code base check out src/org/apache/pig/backend/hadoop/executionengine/mapReduceLayer/MRCompiler.java and src/org/apache/pig/backend/hadoop/executionengine/mapReduceLayer/JobControlCompiler.java
These are the classes the control the generation of MapReduce jobs.
