> Information such as containerId, nodemanager hostname, nodemanager port is not set in the environment when any container is launched. 
> For an AM, the RM does all of this for it but for a container launched by an application, all of the above need to be set by the ApplicationMaster. 
> At the minimum, container id would be a useful piece of information. If the container wishes to talk to its local NM, the nodemanager related information would also come in handy.
