> Don't log duplicate TaskManager registrations as exceptions
> -----------------------------------------------------------
>
> Key: FLINK-3981
> URL: https://issues.apache.org/jira/browse/FLINK-3981
> Project: Flink
> Issue Type: Bug
> Components: ResourceManager
> Affects Versions: 1.1.0
> Reporter: Maximilian Michels
> Assignee: Maximilian Michels
> Priority: Minor
> Labels: test-stability
> Fix For: 1.1.0
>
>
> Duplicate TaskManager registrations shouldn't be logged with Exceptions in
> the ResourceManager. Duplicate registrations can happen if the TaskManager
> sends out registration messages too fast when the actual reply is not lost
> but still in transit.
> The ResourceManager should simply acknowledge the duplicate registrations,
> leaving it up to the JobManager to decide how to treat the duplicate
> registrations (currently it will send an AlreadyRegistered to the
> TaskManager).
> This change also affects our test stability because the Yarn tests check the
> logs for exceptions.
