Description

When I submit a Pyspark program with spark-submit command this error is thrown.

It happens when for code like below

RDD2 = RDD1.map(lambda m: function_x(m)).reduceByKey(lambda c,v :c+v)

or

RDD2 = RDD1.flatMap(lambda m: function_x(m)).reduceByKey(lambda c,v :c+v)

or
RDD2 = RDD1.flatMap(lambda m: function_x(m)).reduce(lambda c,v :c+v)

pickle.PicklingError: args[0] from __newobj_ args has the wrong class

I tried replacing the cloudpickle code from GitHub , but that started giving error copy_reg not defined and copyreg not defined .(for both python 2.7 and 3.5)
