Hi,  
I've set all those parameters :  
settingBuilder.put("discovery.type", "ec2");  
settingBuilder.put("cloud.account","....");  
settingBuilder.put("cloud.key", ".....");  
settingBuilder.put("compute.type", "amazon");  
settingBuilder.put("logger.discovery", "TRACE");

and called  
NodeBuilder nodeBuilder().settings(setting).clusterName("caindexcluster").client(true).node();

After few second i got next message : [Warhawk] waited for 30s and no  
initial state was set by the discovery  
and then exception org.elasticsearch.discovery.MasterNotDiscoveredException:  
I tried to put discovery log to TRACE by setting  
this settingBuilder.put("logger.discovery", "TRACE");, but it's doesn't  
seems to work.

First question how can I enable ES log for the discovery in the java to  
TRACE  
And second , what did I miss in the configuration params.

The cluster itself is running and from the same server where this java code  
is executed calling  
curl -XGET '[http://10.190.224.44:9200/\_cluster/state?pretty=1](http://10.190.224.44:9200/_cluster/state?pretty=1)' returns:

{  
"cluster\_name" : "indexcluster",  
"master\_node" : "SHE8gNd2TY-r9GLHDtO-YQ",  
"blocks" : {  
},  
"nodes" : {  
"SHE8gNd2TY-r9GLHDtO-YQ" : {  
"name" : "Tyrannosaur",  
"transport\_address" : "inet[/10.190.224.44:9300]",  
"attributes" : {  
}  
},  
"9nCpGOiOSUuksGwTeWwTDQ" : {  
"name" : "Krystalin",  
"transport\_address" : "inet[/10.190.239.76:9300]",  
"attributes" : {  
}  
}  
},  
"metadata" : {  
"templates" : {  
},  
"indices" : {  
}  
},  
"routing\_table" : {  
"indices" : {  
}  
},  
"routing\_nodes" : {  
"unassigned" : [],  
"nodes" : {  
}  
},  
"allocations" : []  
}

Thank You.

When you are running elasticsearch embedded in your Java app, it will  
automatically use whatever logging you are using. So, configure the logging  
in your app logging config, and note, when running embedded, the logging  
categories are prefixed with org.elasticsearch.
