Arun Suresh updated YARN-4876:
------------------------------
Description:
Introduce *initialize* and *destroy* container API into the
*ContainerManagementProtocol* so decouple the actual start of a container from
the initialization. This will allow AMs to re-initialize and re-start a
container without having to lose the allocation.
Additionally, if the localization of the container is associated to the
initialize (and the cleanup with the destroy), This can also be used by
applications to upgrade a Container by re-initializing with a new
*ContainerLaunchContext*
