--------------------------------------
Is this JIRA still being actively worked on? If not, I'd like to drop the priority to Major.

> Related to HADOOP-11656, we would like to make a number of improvements in terms of classloading isolation so that user-code can run safely without worrying about dependency collisions with the Hadoop dependencies.
> By the same token, it should raised the quality of the user code and its specified classpath so that users get clear signals if they specify incorrect classpaths.
> This will contain a proposal that will include several improvements some of which may not be backward compatible. As such, it should be targeted to the next major revision of Hadoop.
