Typically users ssh edge node which is co-located with the cluster. It also
minimizes latency between client and cluster.

In my experience you build a node called Edge Node which has all the
libraries and configuration setting in XML to connect to the cluster, it
just doesn't have any of the Hadoop daemons running.

We’ve found that much of the Hadoop samples assume that running is being
done form a cluster node, and that the connection information can be
gleaned directly from a configuration object. However, we always run our
client from a remote computer, and our users must manually specify the
NN/RM addresses and ports. We’ve found this varies maddeningly between
distros and especially on hosted virtual implementations. Getting the
wrong port results in various inscrutable errors with red-herring messages
about security. Is there a prescribed way to get the correct connection
information more easily, like from a web API (where at least we’d only need
one address and port)?
