Interface ContainerToken

All Superinterfaces:

Token

@InterfaceAudience.Public
@InterfaceStability.Stable
public interface ContainerToken
extends Token

ContainerToken is the security token used by the framework to verify authenticity of any Container.

The ResourceManager, on container allocation provides a secure token which is verified by the NodeManager on container launch.

Applications do not need to care about ContainerToken, they are transparently handled by the framework - the allocated Container includes the ContainerToken.
