> The new logical plan fails when I have complex data types returning from my eval function.
> The below is my script :
> {code}
> register myudf.jar;   
> B1 = load 'myinput' as (id:chararray,ts:int,url:chararray);
> B2 = group B1 by id;
> B = foreach B2 {
>  Tuples = order B1 by ts;
>  generate Tuples;
> };
> C1 = foreach B generate TransformToMyDataType(Tuples,-1,0,1) as seq: { t: ( previous, current, next ) };
> C2 = foreach C1 generate FLATTEN(seq);
> C3 = foreach C2 generate  current.id as id;
> dump C3;
> {code}
> On C3 it fails with below message :
> {code}
> Couldn't find matching uid -1 for project (Name: Project Type: bytearray Uid: 45 Input: 0 Column: 1)
> {code}
> The below is the describe on C1 ;
> {code}
> C1: {seq: {t: (previous: (id: chararray,ts: int,url: chararray),current: (id: chararray,ts: int,url: chararray),next: (id: chararray,ts: int,url: chararray))}}
> {code}
> The script works if I turn off new logical plan or use Pig 0.7.
