Can you check whether you have multiple versions of the offending
class (org.apache.spark.SerializableWritable) in the classpath of your
apps? Maybe you do and different nodes are loading jars in different
I checked all the org.apache.spark.SerializableWritable classes and all
of them have the same
serialVersionUID

That means not all of your driver and executors have the same version of
Spark. Are you on a standalone EC2 cluster? If so, one way to fix this is to
run the following on the master node:
/root/spark-ec2/copy-dir --delete /root/spark
This syncs all of Spark across your cluster, configs, jars and everything.

Hi,
I get the following exception when using Spark to run various programs.
