I have Flink 1.2.1 running on Docker, with Task Managers distributed across different VMs as part of a Docker Swarm.
I understand Dynamic Scaling is not yet available in Flink. Therefore, if I wanted to increase the number of containers running Flink's task manager (scale up), I would need to create a savepoint, stop the running job, scale up my Task Manager containers, then resume the job. My question is: how do I create a savepoint? The documentation assumes you are using the Command Line Client, but I don't think I can access it if I am running Flink in containers. The Web UI doesn't allow you to create savepoints either. What do I do, in this case? Thank you very much for your help. -- Sent from: http://apache-flink-user-mailing-list-archive.2336050.n4.nabble.com/
