> -----------------------------------------------------------------
>
> Key: YARN-8579
> URL: https://issues.apache.org/jira/browse/YARN-8579
> Project: Hadoop YARN
> Issue Type: Bug
> Affects Versions: 3.1.1
> Reporter: Yesha Vora
> Assignee: Gour Saha
> Priority: Critical
> Fix For: 3.2.0, 3.1.2
>
> Attachments: YARN-8579.001.patch, YARN-8579.002.patch
>
>
> Steps:
> 1) Launch httpd-docker
> 2) Wait for app to be in STABLE state
> 3) Run validation for app (It takes around 3 mins)
> 4) Stop all Zks
> 5) Wait 60 sec
> 6) Kill AM
> 7) wait for 30 sec
> 8) Start all ZKs
> 9) Wait for application to finish
> 10) Validate expected containers of the app
> Expected behavior:
> New attempt of AM should start and docker containers launched by 1st attempt
> should be recovered by new attempt.
> Actual behavior:
> New AM attempt starts. It can not recover 1st attempt docker containers. It
> can not read component details from ZK.
> Thus, it starts new attempt for all containers.
