Robert Joseph Evans commented on MAPREDUCE-2986:
------------------------------------------------
It looks like a good start. In the constructor for the YarnMiniMRCluster I
would prefer to see more code reuse between the two. Perhaps if the original
constructor could just call the new one with a 1 for the number of clusters.
Also I think you will need to update various configs for the different node
managers created. This is so there are no host/port collisions between the
different node managers running on the same box.

> 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.
