> We have the job classloader on the mapreduce tasks that run on the cluster.
> It has a benefit of being able to isolate class space for user code and avoid
> version clashes.
> Although it occurs less often, version clashes do occur on the client JVM. It
> would be good to introduce an isolated classloader on the client side as well
> to address this. A natural point to introduce this may be through RunJar, as
> that's how most of hadoop jobs are run.
