привет,

я прошу меня извенить, но я не в состояние сформулировать мой вопрос по русски, поэтому попытаюсь по англиски.  
Может быть кто-нибудь здесь мне может помочь.

I try to use elasticsearch for "search suggestion" in a java-webapplication.  
There are 2 nodes in the cluster behind a load balancer.  
I use elasticsearch 1.5

My problem is, if I use Transport Client with node host addresses there is no problem.

Client transportClient = new TransportClient(settings())  
.addTransportAddress(new InetSocketTransportAddress("elastic-suggest1.de", 9300))  
.addTransportAddress(new InetSocketTransportAddress("elastic-suggest2.de", 9300));

but if I try to use the load balancer with load balancer host address

Client client = new TransportClient(settings())  
.addTransportAddress(new InetSocketTransportAddress("load\_balancer\_host.de", 80));

I get an error  
elasticsearch[Blue Diamond][transport\_client\_worker][T#20]{New I/O worker #20} deploymentPhase   
WARN org.elasticsearch.transport.netty - [Blue Diamond] exception caught on transport layer [[id: 0x6f6cd7f0, /xx.xxx.xxx.xxx:41411 =\> load\_balancer\_host.de/xx.xxx.xxx.xxx:80]], closing connection

and then  
None of the configured nodes were available: [[suggest1][l6ReVYRRSeqz8CT9aSHnEA][elastic-suggest1.de][inet[load\_balancer\_host.de/xx.xxx.xxx.xxx:80]]]

Can somebody help me to find a solution for this problem?

Спасибо,  
Таня

Не был уверен на каком языке отвечать, поэтому ответил в английском в английской категории 😄

Да, пока что официального REST клиента для java нет.
