Conditional execution of 'generate' clauses
Hi Folks,

I came across a use case where I'd like to do something like this:

   t = DISTINCT (...)
   if (!IsEmpty(t))
      GENERATE foo, ...

Thus, 'generate' is conditionally executed and the control flow depends on
the value of some tuple 't'.
Can this be done in pig?



P.S. Please ignore my previous email; I accidentally triggered send before I
