>
> The current hadoop environment assumes that everything is trusted
> environment and so doesn't have any security checks. This might lead to any
> one to spoof as super user and gain access to the cluster if the environment
> is open for every one. So, there is a need to restrict super user permission
> only from certain IP addresses.
