> 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.
