----------------------------------------
I tried to address the ports issue in my revised patch (attached) by using port
0, but I am failing unit tests because the NMs fail to start properly. Could
someone help debug the problem I am running into? Also attaching the log for
this failure.

> The current MiniYARNCluster can only support 1 node manager, which is not
> enough for the full test purposes.
> Would like to have a simulator that can support multiple node managers as the
> real scenario. This might be beneficial for hadoop users, testers and
> developers.
