Some things to think about:
- Do we want an option for this (e.g. as for ganglia)? I haven't done this
as I think it would be confusing at the moment, since a user would assume that
the option would enable the hdfs nfs gateway on the cluster. However as far as
I'm aware, spark-ec2 doesn't do this yet (#6601). So I think it would be better
if the option were added as part of that work.
- Further, since the ports are opened to the authorized address, I don't
see a problem in having this done by default for now.
I have tested this with a spark-ec2 cluster running the gateway (i.e. with
these settings, I can mount the hfds on my local machine - which is really
handy!)
