> When AM calls NM via {{ContainerManagementProtocol}}, the NMToken is suppied
> for authentication. The RPC server will verify the password of NMToken
> (originally generated by RM) so that we know the content of NMTokenIdentifier
> is geniune.
> Next, for {{stopContainers()}} and {{getContainerStatus()}}, method
> {{authorizeGetAndStopContainerRequest()}} is used to verify that the requsted
> containers do belong to the AM by comparing them against the AppId in
> NMTokenIdentifier. However, right now when the appId doesn't match,
> {{authorizeGetAndStopContainerRequest()}} only log a warning message and
> continues to kill the container... Overall a malicious AM can kill containers
> of other apps running in any node its containers are running.
