NoNodeAvailableException

Question - does the client need to be able to connect to all the nodes
in a cluster, or just one?

We set up a two-node cluster, but only made one node available outside
of our production firewall. I can connect to that node using curl and
run queries, but when I try to connect programatically via the Java
API, I get the "NoNodeAvailable" exception. With additional logging
enabled, I see this in my output:

Only one node is enough. It seems like it failed ot resolve the address you
provided the TransportClient. Did you enable sniffing? If so, it will try
and connect to the publish host of the node (logged when it starts up), not
the address you provided.

but only made one node available outside of our production firewall.

also ensure you have the port 9300 available + equal version on client
and server
