Shravan Matthur Narayanamurthy updated PIG-382:
-----------------------------------------------
Status: Patch Available (was: Open)
Fixed the issue mentioned where implicit casts are not being inserted for
BinCond.
Also there was another bug in the parser where it did not set the type of Const
in RegExp. That is also fixed in this patch.
However, there is another issue where the typechecking happens only on dump,
which is reported in the bug. I think this is a separate bug unrelated to
BinCond. I will create a new bug for that. It needs changes to the execution
codepaths in PigServer. Will track this with the new bug.
> bincond does not performa implicit cast of parameters

> The following script

> grunt> B = foreach A generate ((name matches 'bob') ? name : '');
> grunt> dump B;
> produces error below. Also, I am not sure why the error is not produce after
> just the second line. You need dump to see the error
