> ------------------------------
>
> Key: FLINK-10137
> URL: https://issues.apache.org/jira/browse/FLINK-10137
> Project: Flink
> Issue Type: Improvement
> Components: Distributed Coordination, ResourceManager, YARN
> Affects Versions: 1.5.2, 1.6.0
> Reporter: Gary Yao
> Assignee: Gary Yao
> Priority: Major
> Labels: pull-request-available
>
> Currently the Flink logs do not reveal why a YARN container completed.
> {{YarnResourceManager}} should log the {{ContainerStatus}} when the YARN
> ResourceManager reports containers to be completed.
> *Acceptance Criteria*
> * {{YarnResourceManager#onContainersCompleted(List<ContainerStatus>)}} logs
> completed containers.
> * {{ResourceManager#closeTaskManagerConnection(ResourceID, Exception)}}
> should always log the message in the exception.
