We have a requirement to add a new gateway to hadoop cluster in additional to the one we already have. I have a couple of queries if anyone can help.
1. Are there any concerns in adding multiple gateways to a CDH cluster?
2. I came across the below article describing how to set up a gateway outside the cluster.
We have a kerberized cluster. Is it recommended to set up a gateway outside and will it be possible to submit jobs from this external gateway? (We have Oozie and Httpfs services running in a different host within the cluster). Are there any disadvantages to this approach?
Thank you in advance for your valuable inputs.

@roczei Thank you for your response.
Do you mean to say that functionally, there will be no difference in a gateway set up outside? I can submit applications and access HDFS as I would do from a gateway within the cluster, correct?
