> When using cgroups we require LCE to be configured in the cluster to start
> containers.
> When LCE starts containers as the user that submitted the job. While this
> works correctly in a secure setup, in an un-secure setup this presents a
> couple issues:
> * LCE requires all Hadoop users submitting jobs to be Unix users in all nodes
> * Because users can impersonate other users, any user would have access to
> any local file of other users
> Particularly, the second issue is not desirable as a user could get access to
> ssh keys of other users in the nodes or if there are NFS mounts, get to other
> users data outside of the cluster.
