[jira] [Created] (PIG-2596) Jython UDF does not handle boolean
output
Jython UDF does not handle boolean output
-----------------------------------------
Key: PIG-2596
URL: https://issues.apache.org/jira/browse/PIG-2596
Project: Pig
Issue Type: Bug
Reporter: Daniel Dai
When a Jython UDF returns boolean, we still get integer object in Pig, through describe show the right boolean type.
Jython UDF:
{code}
@outputSchema("retired:boolean")
def isretired(age):
if age == None:
return None
elif age>=60:
return True
else:
return False
{code}
Pig script:
{code}
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;
{code}
