-----------------------------------------

One of the test failures ( {{TestPrivilegedOperationExecutor}} ) is unrelated 
to this patch. Please see the update to YARN-2194

> For security reasons, we need to ensure that access to the docker daemon and 
> the ability to run docker containers is restricted to privileged users ( i.e 
> users running applications should not have direct access to docker). In order 
> to ensure the node manager can run docker commands, we need to add docker 
> support to the container-executor binary.
