> Issue Type: Bug
> Reporter: Guozhang Wang

>
> Today we use a single class loader for both framework classes as well as user
> code (StreamTask implementations), which could result in conflicts of
> dependencies.
> The approach is to use separate class loaders for framework classes and user
> instantiated classes. This approach has also been applied in Hadoop and Spark
> (MAPREDUCE-1700, SPARK-1870).
