Subject Re: Flink Mesos task management

Hi Jared,

the way to solve this problem at the moment is to take a savepoint of your
job, restart the cluster with the updated Docker image and then resubmit
the job starting from the most recent savepoint. The same applies when you
want to change the parallelism of your job.

We are currently working on improving Flink's dynamic scaling capabilities
such that you have a command which let's you directly scale up or down a
job. Depending on the available resources this also will allocate or
deallocate new tasks from Mesos/Yarn.
