> When a CGS node is present and gets replaced by a FGS node after a flex-down and flex-up, the memory calculation is going wrong. I see the applications hang and the AM container fails to get scheduled.
> By default when a NM is started, it is started on a random port. Only the web server port is fixed to 8042. 
> The behavior should be similar in Myriad. We need to randomize the port of the NM from the offer obtained from mesos. So when we flex down and flex-up it starts on a different port. Otherwise Myriad considers this as the same NM with different resources. Hence the memory calculation issue.
