Unicast Problems (no handler found for action [discovery/zen/unicast])

[Marc_Seeger]

I'm trying to get the cluster working on EC2 (without the cloud
plugin).

1. I start server A
2. I put the elastic ip of server A in server B's config file (in the
   unicast options)

discovery.zen.ping.multicast:
enabled: false

discovery.zen.ping.unicast:
hosts: ["ec2-xxx-xx-xx-xxx.compute-1.amazonaws.com:9300"]

3. I start server B
4. server B tries to connect to server A and disaplys a a null pointer
   exception:

[02:30:49,691][WARN ][discovery.zen.ping.unicast] [Mad Thinker] Failed

Is there anything I'm missing?

In the initial config, the port is the same as in the error messages
(3001)

I have fixed the NPE, but the problem is still there. You need to configure
a list of hosts on both nodes (it can be a static list that includes both
nodes elastic ips, thats fine). The unicast ping is not started when there
is no list of hosts.
