Kyle Birch updated DATAFU-83:
-----------------------------
    Attachment: rb36702.patch

Since this hasn't been addressed in a while, I'm interested in helping out. Here is the most up-to-date patch that you can find on the RB. I addressed the indentation issue, even though I haven't posted it over at the RB, yet.

> 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}
