bincond does not performa implicit cast of parameters
-----------------------------------------------------

Key: PIG-382
URL: https://issues.apache.org/jira/browse/PIG-382
Project: Pig
Issue Type: Bug
Affects Versions: types_branch
Reporter: Olga Natkovich
Fix For: types_branch


The following script

grunt> A = load 'foo' as (name, age, gpa);
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

    Shravan Matthur Narayanamurthy commented on PIG-382:
    ----------------------------------------------------

    Two parts:
    1) Why did it not complain earlier?
    This is also related to the GruntParser using things separately. From GruntParser we only call registerQuery which does not call execute unless it hits a store. Execute gets called directly from grunt only from processDump(). We need to do type checking inside registerQuery and not in execute if we want to see the behavior we are expecting.

    2) I still need to look at the binCond issue

    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.
