Eyal Allweil commented on DATAFU-83:
------------------------------------
By the way, [~ItsAUsernameRight?], if you're already looking at InUDF, and
you'd like another contribution afterwards, you can also look at
[DATAFU-80|https://issues.apache.org/jira/browse/DATAFU-80] - it's another
small change to improve InUDF's behavior. (you can ignore the second part of
that issue, which deals with Java versions).
> InUDF does not validate that types are compatible

> See the example below. The input data is a long, but ints are provided to
> match against. Because it uses the Java equals to compare and these are
> different types, this will never match, which can lead to confusing results.
> I believe it should at least throw an error.
> {code}
> define I datafu.pig.util.InUDF();
>
> data = LOAD 'input' AS (B: bag {T: tuple(v:LONG)});
>
> data2 = FOREACH data {
> C = FILTER B By I(v, 1,2,3);
> GENERATE C;
> }
>
> describe data2;
>
> STORE data2 INTO 'output';
> {code}
