> There are no documentations for some of the Optimization Rules,
> For ex; ColumnMapKeyPrune
> in http://pig.apache.org/docs/r0.8.1/piglatin_ref1.html#Optimization+Rules
> And moreover I believe the documentaion should be saying how to disable these
> rules using -t option.
> It would be nice if the documentation could talk of some uses cases where it
> makes sense to disable the optimization rule.
