NullPointerException when I have multiple python udfs -----------------------------------------------------
Key: PIG-2404 URL: https://issues.apache.org/jira/browse/PIG-2404 Project: Pig Issue Type: Bug Affects Versions: 0.8.1, 0.9.1 Reporter: Vivek Padmanabhan When I have multiple python udfs registered, the script fails at compile phase while trying to get the udf ouputschema. {code} register 'a.py' using org.apache.pig.scripting.jython.JythonScriptEngine as a_func; register 'b.py' using org.apache.pig.scripting.jython.JythonScriptEngine as b_func; a = load 'i1' as (f1:chararray); b = foreach a generate a_func.helloworld(), b_func.square(3); dump b; {code} a.py {code} @outputSchema("word:chararray") def helloworld(): return 'Hello, World' {code} b.py {code} @outputSchemaFunction("squareSchema") def square(num): return ((num)*(num)) {code} Moreover , in the log we can see duplicate and incorrect registration of udfs which I believe the cause for the script failure.
