---------------------------------
Hi [~till.rohrmann] Can you tell me what's your opinion now?
> Flink should provide a mechanism to prevent scheduling tasks on TaskManagers
> with operational issues
> ----------------------------------------------------------------------------------------------------
>
> Key: FLINK-5621
> URL: https://issues.apache.org/jira/browse/FLINK-5621
> Project: Flink
> Issue Type: New Feature
> Components: Runtime / Coordination
> Affects Versions: 1.1.4
> Reporter: Jamie Grier
> Assignee: vinoyang
> Priority: Major
>
> There are cases where jobs can get into a state where no progress can be made
> if there is something pathologically wrong with one of the TaskManager nodes
> in the cluster.
> An example of this would be a TaskManager on a machine that runs out of disk
> space. Flink never considers the TM to be "bad" and will keep using it to
> attempt to run tasks -- which will continue to fail.
> A suggestion for overcoming this would be to allow an option where a TM will
> commit suicide if that TM was the source of an exception that caused a job to
> fail/restart.
> I'm sure there are plenty of other approaches to solving this..
