-------------------------------------------------------------
Attached are the logs of container 3 that fails to re-initialize. When it is
re-initialized, the container is stopped and cleanup. This causes the container
to exit but here it exits with code {{255}} instead of {{FORCE_KILLED}} or
{{TERMINATED}}.
Since the container exits with a failure code, that is {{255}}, the status of
the container in NM changes from {{REINITIALIZING_AWAITING_KILL}} to
{{EXITED_WITH_FAILURE}}.
Below are the relevant log stmts:
1. Reinit of the container is triggered

> Yarn Service Upgrade: Support upgrade of service that use docker containers
> ----------------------------------------------------------------------------
>
> Key: YARN-8160
> URL: https://issues.apache.org/jira/browse/YARN-8160
> Project: Hadoop YARN
> Issue Type: Sub-task
> Reporter: Chandni Singh
> Assignee: Chandni Singh
> Priority: Major
> Labels: Docker
> Attachments: container_e02_1533231998644_0009_01_000003.nm.log

> Ability to upgrade dockerized yarn native services.
> Ref: YARN-5637
> *Background*
> Container upgrade is supported by the NM via {{reInitializeContainer}} api.
> {{reInitializeContainer}} does *NOT* change the ContainerId of the upgraded
> container.
> NM performs the following steps during {{reInitializeContainer}}:
> - kills the existing process
> - cleans up the container
> - launches another container with the new {{ContainerLaunchContext}}
> NOTE: {{ContainerLaunchContext}} holds all the information that needs to
> upgrade the container.
> With {{reInitializeContainer}}, the following does *NOT* change
> - container ID. This is not created by NM. It is provided to it and here RM
> is not creating another container allocation.
> - {{localizedResources}} this stays the same if the upgrade does *NOT*
> require additional resources IIUC.
>
> The following changes with {{reInitializeContainer}}
> - the working directory of the upgraded container changes. It is *NOT* a
> relaunch.
> *Changes required in the case of docker container*
> - {{reInitializeContainer}} seems to not be working with Docker containers.
> Investigate and fix this.
> - [Future change] Add an additional api to NM to pull the images and modify
> {{reInitializeContainer}} to trigger docker container launch without pulling
> the image first which could be based on a flag.
> -- When the service upgrade is initialized, we can provide the user with
> an option to just pull the images on the NMs.
> -- When a component instance is upgrade, it calls the
> {{reInitializeContainer}} with the flag pull-image set to false, since the NM
> will have already pulled the images.
