Pig >> mail # user >> pig generated 2 map-only jobs ?


Copy link to this message

pig generated 2 map-only jobs ?
this is what happened with my pig script.
why would it generate 2 map-only jobs?
wouldn't the optimization process chain together both mappers and keep only
1 mapper stage?
thanks
Yang
