though it should be immutable
Jonathan Arfa created SPARK-6902:
------------------------------------
Summary: Row() object can be mutated even though it should be immutable
Key: SPARK-6902
URL: https://issues.apache.org/jira/browse/SPARK-6902
Project: Spark
Issue Type: Bug
Components: PySpark, SQL
Affects Versions: 1.2.0
Reporter: Jonathan Arfa
See the below code snippet, IMHO it shouldn't let you assign {{x.c = 5}} and should just give you an error.
