Alan Gates commented on PIG-3199:
---------------------------------
Take a look at PigNotificationListener.initialPlanNotification. It seems like
this will give you what you want, since each of the sources and sinks for the
MR jobs are in here. To my chagrin this exposes the MR plan. Someone snuck
that past me.
