                 Key: SPARK-23141
                 URL: https://issues.apache.org/jira/browse/SPARK-23141

Currently {{UDFRegistration.registerJavaFunction}} doesn't support data type string as a returnType whereas {{UDFRegistration.register}}, {{@udf}}, or {{@pandas_udf}} does.
 We can support it for {{UDFRegistration.registerJavaFunction}} as well.
