Is there any workaround to distribute non-serializable object for RDD transformation or broadcast variable ?
Say I have an object of class C which is not serializable. Class C is in a jar package, I have no control on it. Now I need to distribute it either by rdd transformation or by broadcast. I tried to subclass the class C with Serializable interface. It works for serialization, but deserialization does not work, since there are no parameter-less constructor for the class C and deserialization is broken with an invalid constructor exception. I think it's a common use case. Any help is appreciated. -- Hao Ren Data Engineer @ leboncoin Paris, France
