URL: https://issues.apache.org/jira/browse/SPARK-11159
Project: Spark
Issue Type: Bug
Components: SQL
Affects Versions: 1.5.1

I'm running spark 1.5.1 and getting the following error:
{{java.lang.UnsupportedOperationException: Cannot evaluate expression:
PythonUDF#func_db_v1863(9999)}} whenever I run a query like: {{SELECT
func_format_v1863(func_db_v1863('9999')) as ds261_v1869 FROM df1}} after
registering {{func_db_v1863}} and {{func_format_v1863}} as functions.
