[jira] Created: (PIG-1837) Error while using IsEmpty function

Error while using IsEmpty function
----------------------------------

                 Key: PIG-1837
                 URL: https://issues.apache.org/jira/browse/PIG-1837
             Project: Pig
          Issue Type: Bug
          Components: impl
    Affects Versions: 0.9.0
            Reporter: Olga Natkovich
             Fix For: 0.9.0


I have the following 2 inputs:

data1: 
1       11
2       15

data2:
1       10
4       11
5       10

And the following script to work on the data:

grunt> A = load 'data1' as (x, y: int);
grunt> B = load 'data2' as (x, z: int);
grunt> C = cogroup A by x, B by x;
grunt> D = foreach C generate group, SUM(((IsEmpty(A.y))? {(0)} : A.y)) + SUM (((IsEmpty(B.z))? {(0)} : B.z));
grunt> dump D;

After running for a while, I get the following error:

Backend error : org.apache.pig.builtin.IsEmpty cannot be cast to org.apache.pig.Accumulator
