Connecting by means of Java Client and Proxy

Elastic Stack Elasticsearch
1

All,

I am attempting to make a connection to my 1 node cluster by means of the
Java Client. but when i do i get the following exception:
INFO: [Marvin Flumm] failed to get local cluster state for
[#transport#-1][flatback][inet[hostnamel/ipnumber:80]], disconnecting...
org.elasticsearch.transport.ReceiveTimeoutTransportException:
[][inet[hostnamel/ipnumber:80]][cluster/state] request_id [0] timed out
after [5000ms]

at
java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617)
at java.lang.Thread.run(Thread.java:744)

In my apache log file i see this:
[Thu Apr 24 00:02:59 2014] [error] proxy: HTTP: disabled connection for
(localhost)
[Thu Apr 24 00:25:55 2014] [error] (111)Connection refused: proxy: HTTP:

[Thu Apr 24 00:40:57 2014] [error] ap_proxy_connect_backend disabling
worker for (localhost)

all this spoken, how do i connect with the java client to the elastic
server by means of the Java API with a proxy in place. tools like Marvel
work fine. When looking at the apache log, it seems to mee it is trying to
connect by means of a different port??

any suggestions are appreciated!

Pieter

Just a note: Java client uses Transport Layer (default to 9300 port) and not HTTP layer (default to 9200 port).

I think you are trying to set transport to HTTP layer (80 port).

Te si do try and Connect by means of port 80 but thuis is forwarded by my proxy to 9300.

You mean it Ignores the port settings in THE transport client?

I think I'm missing something here.
So you have a proxy which redirect queries to port 80 to port 9300, right?

I think this should work.

But if Marvel interface works fine using localhost:80/_plugin/marvel URL, it means to me that you redirected 80 port to 9200 port.

Note that when using Transport Java Client, you need to define the same cluster name as you defined in your nodes.

Thus,

calling http://domaina.myHost9200:80/_nodes/ results in:
"cluster_name" : "elasticsearch",
"nodes" : {
"ER0q2vqdSleZpnKdi51_SQ" : {
"name" : "Baron Strucker",
"transport_address" : "inet[hawksbill.local/192.168.1.142:9300]",
"host" : "hawksbill.domainb",
"ip" : "127.0.1.1",
"version" : "1.0.2",
"build" : "4fc0da7",
"http_address" : "inet[/192.168.1.142:9200]",

(note domaina and domainb are not equal)

connecting with:

Settings settings = ImmutableSettings.settingsBuilder()
.put("cluster.name", "Baron Strucker").build();

Client client = new TransportClient(settings)
.addTransportAddress(new InetSocketTransportAddress("domainA.myhost9300", 80))

Should do the tric? Currently i'm working for my boss, but will try this later today.
