… with KryoSerializer This PR fixes an issue where PySpark broadcast variables caused NullPointerExceptions if KryoSerializer was used. The fix is to register PythonBroadcast with Kryo so that it's deserialized with a KryoJavaSerializer. Author: Josh Rosen <joshrosen@databricks.com> Closes #3831 from JoshRosen/SPARK-4882 and squashes the following commits: 0466c7a [Josh Rosen] Register PythonBroadcast with Kryo. d5b409f [Josh Rosen] Enable registrationRequired, which would have caught this bug. 069d8a7 [Josh Rosen] Add failing test for SPARK-4882 (cherry picked from commit efa80a5) Signed-off-by: Josh Rosen <joshrosen@databricks.com>
