Description

When a Jython UDF returns boolean, we still get integer object in Pig, through describe show the right boolean type.
Jython UDF:

@outputSchema("retired:boolean")
def isretired(age):
    if age == None:
        return None
    elif age>=60:
        return True
    else:
        return False

Pig script:

register 'scriptingudf.py' using jython as myfuncs;
a = load 'student.txt' as (name:chararray, age:int, gpa:double);
b = foreach a generate name, myfuncs.isretired(age);
describe b;
dump b;
