Chandni Singh updated YARN-8160:
--------------------------------
    Description: 
Ability to upgrade dockerized  yarn native services.

Ref: YARN-5637

Ref: YARN-5637
Ability to upgrade dockerized  yarn native services.

Container upgrade is supported by the NM via {{reInitializeContainer}} api. 
{{reInitializeContainer}} does *NOT* change the ContainerId of the upgraded 
container.
{{reInitializeContainer}} of the container on the NM performs these steps:
- kill the existing process
- cleanup the container
- launch another container with the new {{ContainerLaunchContext}}

The Container Id does NOT change because NM doesn't create the ContainerId. It 
is provided to it by the AM and here the RM is not involved in creating a new 
container allocation.
