@InterfaceAudience.Public @InterfaceStability.Stable public abstract class ContainerLaunchContext extends Object
ContainerLaunchContext
represents all of the information
needed by the NodeManager
to launch a container.
It includes details such as:
ContainerId
of the container.Resource
allocated to the container.LocalResource
necessary for running the container such
as binaries, jar, shared-objects, side-files etc.

Get application-specific binary service data. This is a map keyed
