---------------------------------------
Summary: Spark SQL UDF does not work with struct input parameters
Key: SPARK-12809
URL: https://issues.apache.org/jira/browse/SPARK-12809
Project: Spark
Issue Type: Bug
Components: SQL
Affects Versions: 1.6.0
Reporter: Deenar Toraskar
Spark SQL UDFs dont work with struct input parameters
def testUDF(expectedExposures: (Float, Float))= {
(expectedExposures._1 * expectedExposures._2 /expectedExposures._1)
}
sqlContext.udf.register("testUDF", testUDF _)
sqlContext.sql("select testUDF(struct(noofmonths,ee)) from netExposureCpty")
The full stacktrace is given below
com.databricks.backend.common.rpc.DatabricksExceptions$SQLExecutionException:
org.apache.spark.sql.AnalysisException: cannot resolve
'UDF(struct(noofmonths,ee))' due to data type mismatch: argument 1 requires
struct<_1:float,_2:float> type, however, 'struct(noofmonths,ee)' is of
struct<noofmonths:float,ee:float> type.; line 1 pos 33
