> In Hadoop-free mode, Hadoop isn't on the classpath.  The Mesos job manager normally uses
the Hadoop UserGroupInformation class to overlay a user context (`HADOOP_USER_NAME`) for the
task managers.  
> Detect the absence of Hadoop and skip over the `HadoopUserOverlay`, similar to the logic
in `HadoopModuleFactory`.    This may require the introduction of an overlay factory.
