> 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)
