[jira] [Commented] (SPARK-4726) NotSerializableException thrown on
SystemDefaultHttpClient with stack not related to my functions
[ https://issues.apache.org/jira/browse/SPARK-4726?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14233933#comment-14233933 ]
Patrick Wendell commented on SPARK-4726:
----------------------------------------
Is it possible that one of your classes has a field that refers to SystemDefaultHttpClient indirectly? Every member of every class you have needs to be transitively serializable.
