Hello,

We run flink as a standalone cluster. When moving from flink 1.3 to 1.6, we 
noticed a change in the scheduling behavior. Where previously parallel subtasks 
of a job seemed to be round-robin allocated around our cluster, flink 1.6 
appears to want to deploy as many subtasks to the same host as possible. This 
model is not as good for our use case, and is causing memory issues for us.

Is there any way to configure flink 1.6 to deploy in the old style? Or if we 
upgraded to 1.7, does that open any doors back towards the model we want?

Thanks,

Andrew
