> Project: Apache Twill
> Issue Type: Bug
> Components: yarn
> Affects Versions: 0.1.0-incubating
> Reporter: Terence Yim
> Assignee: Terence Yim
> Priority: Critical
> Fix For: 0.2.0-incubating

>
> Currently if the the ZK session of the AM is expired, the YarnTwillController
> treats the application stopped and requests YARN to stop the app, which is
> undesirable.
> To make application resilience to ZK failure, the controller should resort to
> polling YARN for the application status until the AM reconnected with ZK.
