Akhil, Andry, thanks a lot for your suggestions. I will take a look to those JVM options.

Greetings,

Also check the guides for the JVM option that prints messages for such problems.
Sorry, sent from phone and don't know it by heart :/

A quick fix would be to implement java.io.Serializable in those classes which are causing this exception.



Thanks

Hi all,

I was wondering if someone has conceived a method for debugging "Task not serializable: java.io.NotSerializableException" errors, apart from commenting and uncommenting parts of the program, or just turning everything into Serializable. I find this kind of error very hard to debug, as these are originated in the Spark runtime system.

I'm using Spark for Java.

Thanks a lot in advance,

Juan
