-------------------------------
Summary: [Spark SQL] In pyspark, cannot group by field on UDF
Key: SPARK-3336
URL: https://issues.apache.org/jira/browse/SPARK-3336
Project: Spark
Issue Type: Bug
Components: PySpark, SQL
Affects Versions: 1.1.0
Reporter: kay feng
Running pyspark on a spark cluster with standalone master.
Cannot group by field on a UDF. But we can group by UDF in Scala.
For example:
q = sqlContext.sql('SELECT COUNT(*), MYUDF(foo) FROM bar GROUP BY MYUDF(foo)')
out = q.collect()
I got this exception:
Py4JJavaError: An error occurred while calling o183.collect.
