I'm using temporary UDTFs on Spark 2.2, e.g.
CREATE TEMPORARY FUNCTION myudtf AS 'com.foo.MyUdtf' USING JAR
'hdfs:///path/to/udf.jar';
But when I try to invoke it, I get the following error:
17/06/14 19:43:50 ERROR SparkExecuteStatementOperation: Error running hive
query:
org.apache.hive.service.cli.HiveSQLException:
org.apache.spark.sql.AnalysisException: No handler for Hive UDF
'com.foo.MyUdtf': java.lang.NullPointerException; line 1 pos 7
