Ok. I tried to reproduce it on elasticsearch 1.3.2.
First node started:
bin/elasticsearch -Ddiscovery.zen.ping.multicast.enabled=false
-Des.discovery.zen.ping.unicast.hosts=localhost
[2014-09-18 08:36:05,417][INFO ][cluster.service ] [Crusader]
new_master
[Crusader][i3SU0cwSQeizbN_MUqAXSw][MacBook-Air-de-David.local][inet[/192.168.0.15:9300]],
reason: zen-disco-join (elected_as_master)
Second node (client):
bin/elasticsearch -Ddiscovery.zen.ping.multicast.enabled=false
-Des.discovery.zen.ping.unicast.hosts=localhost -Des.node.data=false
-Des.node.master=false
[2014-09-18 08:36:36,444][INFO ][cluster.service ] [Sekhmet]
detected_master
[Crusader][i3SU0cwSQeizbN_MUqAXSw][MacBook-Air-de-David.local][inet[/192.168.0.15:9300]],
added
{[Crusader][i3SU0cwSQeizbN_MUqAXSw][MacBook-Air-de-David.local][inet[/192.168.0.15:9300]],},
reason: zen-disco-receive(from master
[[Crusader][i3SU0cwSQeizbN_MUqAXSw][MacBook-Air-de-David.local][inet[/192.168.0.15:9300]]])
So to me everything is working fine.
I don't understand what you are exactly doing. May be you should try to change
logging.yml to DEBUG or TRACE and see what's going on in your client node.

And when you remove -Des.node.master=false the client node is able to join the
cluster?
I mean "join" the cluster so you can see it joining in the master node logs.

Yes.
The settings are almost same for all nodes
discovery.zen.ping.multicast.enabled: false # this is in elasticsearch.yml
-Des.discovery.zen.ping.unicast.hosts=<myCommaSeparatedHostList> this is java
-D parameter

When you start the client node, did you set list of master nodes as unicast
hosts?

Are you using multicast or unicast or a plugin for discovery?

Sorry I didn't explain clearly. I have a cluster with 12 nodes. 10 are master
eligible. 2 are client only (es.node.data=false, es.node.master=false). I have
configured the minimal number of nodes to form a cluster is 6. all the boxes
hosting 12 es instances are on the same rack. The problem is that these two
client-only nodes cannot join the cluster. It cannot discovers the master. But
if I make them master eligible it discover the master node immediately.
I don't understand what make the differences.
Thanks,
Jack

A cluster needs a master node.
You need at least one node which could be elected as master.

I have two nodes with this configuration -Des.node.data=false
-Des.node.master=false when I start. But these nodes have experiencing finding
master node. Here is message.
[2014-09-17 16:51:10,457][WARN ][discovery ] [mynodename] waited
for 30s and no initial state was set by the discovery
However, If I remove -Des.node.master=false.
The discovery have no issue.
