Bharath Bhushan commented on SPARK-1403:
----------------------------------------

In 0.9.0 I see that the classLoader is 
org.apache.spark.repl.ExecutorClassLoader (in SparkEnv.scala)
In 1.0.0 I see that the classLoader is null. My guess is that this should not 
be null.

>  java.lang.ClassNotFoundException - spark on mesos

> I can run spark 0.9.0 on mesos but not spark 1.0.0. This is because the spark 
> executor on mesos slave throws a  java.lang.ClassNotFoundException for 
> org.apache.spark.serializer.JavaSerializer.
