Explain Plan in Pig

Hi Guys,

Can anyone please tell me how to read Explain plan in pig? When I do explain
plan for any of my pig query it gives me really good flow diagram, but it
uses some Pig functions so didn' t really understand what going on and what
it mean.

Please let me if there is any documentation for this.

Thanks,
Sonia

I didn't know about the -e explain option! That's massively helpful.
Thanks Alan.
