Hi
Is there a possibility to gracefully remove a taskmanager from a running cluster?
My idea would be to trigger affected jobs to restart via a savepoint on the remaining taskmanagers. When the taskmanager is idle it can be stopped without jobs falling back to an older checkpoint.
Regards
Bernd

Hi Bernd, at the moment this is not supported out of the box by Flink. What you can do is the following: First cancel a job with savepoint. After the job has been terminated, terminate TaskManagers and then resume the job from the savepoint you've just taken. This assumes that you have a single job running on a cluster. If you have multiple jobs running, then you might need to cancel with savepoint every running job. Cheers, Till On Wed, Feb 6, 2019 at 11:54 AM <[hidden email]> wrote:
