Marco Rabozzi updated YARN-4876:
--------------------------------
Attachment: YARN-4876.01.patch
Attaching a prototype patch for the implementation of initializeContainer and
destroyContainers APIs tested on a simple application master. Work in progress
parts and details to sort out are marked as TODO within the code. Let me know
what do you think so that we can reiterate on the patch.
> [Phase 1] Decoupled Init / Destroy of Containers from Start / Stop

> Key: YARN-4876
> URL: https://issues.apache.org/jira/browse/YARN-4876
> Project: Hadoop YARN
> Issue Type: Sub-task
> Reporter: Arun Suresh

>
> Introduce *initialize* and *destroy* container API into the
> *ContainerManagementProtocol* and decouple the actual start of a container
> from the initialization. This will allow AMs to 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*
