Deepak Kumar V commented on PIG-671:
------------------------------------
Here is the final approach:
Include public List<FuncSpec> getArgToFuncMapping() throws FrontendException in
Count.java which will take care of number of arguments , their data types for
COUNT.
I have the patch ready and have tested it. If anyone is not working on it, can
this bug be assigned to me so that i can submit the patch for review.
> typechecker does not throw an error when multiple arguments are passed to
> COUNT
