> Key: YARN-5184
> URL: https://issues.apache.org/jira/browse/YARN-5184
> Project: Hadoop YARN
> Issue Type: Bug
> Components: api
> Affects Versions: 2.8.0, 2.9.0
> Reporter: Karthik Kambatla
> Assignee: Sangjin Lee
> Priority: Blocker
> Attachments: YARN-5184-branch-2.8.01.patch, YARN-5184.01.patch
>
>
> YARN-2882 and YARN-5430 broke compatibility by adding abstract methods to
> ContainerStatus. Since ContainerStatus is a Public-Stable class, adding
> abstract methods to this class breaks any extensions.
> To fix this, we should add default implementations to these new methods and
> not leave them as abstract.
