Till Rohrmann closed FLINK-8066.
--------------------------------
Resolution: Won't Do
> Changed configuration of taskmanagers should recreate them
> ----------------------------------------------------------
>
> Key: FLINK-8066
> URL: https://issues.apache.org/jira/browse/FLINK-8066
> Project: Flink
> Issue Type: New Feature
> Components: Runtime / Coordination
> Reporter: Stephen Gran
> Priority: Minor
>
> When we redeploy the jobmanager to our mesos cluster with changed parameters
> affecting the taskmanagers (eg, change from 1 CPU per TM to 2 CPUs per TM),
> the existing taskmanagers are reused rather than replaced with new
> taskmanagers with new parameters.
> It seems like *recoverWorkers* in
> *org.apache.flink.mesos.runtime.clusterframework.MesosFlinkResourceManager*
> has most of the information it would need to be able to perform this
> convergence, and it doesn't seem like a large amount of work to do the check.
> My concern with starting to work on the issue there is that there may be a
> higher level, perhaps in *FlinkResourceManager* that should perform this work
> on both mesos and yarn. The two implementations look quite different,
> however, so this may be an over eager optimisation best left for later. I'm
> happy to look at a patch for this, but I wanted some input before starting
> the work to see where you thought this should live.
