Hi there,

I am quite new to use Elasticsearch in my Java project to index Reddit post and I am kindly asking for your help.

I have installed Elasticsearch 5.2.0 together with Kibana and logstash. X-Pack was installed for Elasticsearch 5.2 and Kibana, but I was not able to install X-Pack with logstash (Error: Something went wrong when installing x-pack, message can't dup Nilclass)

I left Elasticsearch mostly untouched only changing the cluster name and added a new user.  
Calling localhost:9200 returns

> {  
> "name" : "node-1",  
> "cluster\_name" : "elasticsearch",  
> "cluster\_uuid" : "gC7rZjBcRuu9jm71Kt15AQ",

> "build\_snapshot" : false,  
> "lucene\_version" : "6.4.0"  
> },  
> "tagline" : "You Know, for Search"  
> }

When I now would like to connect my Java application with Elasticsearch I get a

> Exception in thread "main" java.lang.NoSuchFieldError: connectTimeout

After several tries I ended with this approach to connect which produces the Exception

If you would have to guess, I suspect an inconsistency between elasticsearch 5.2.0 with 'org.elasticsearch.client', name: 'transport', version: '5.1.2', but I was not able to find the 5.2.0 version of it.

Can you please help, many thanks in advance  
Marcel

same here! 😰  
I left it completely untouched and just followed the instructions until Step 7. ([Installing X-Pack | X-Pack for the Elastic Stack [6.2] | Elastic](https://www.elastic.co/guide/en/x-pack/current/installing-xpack.html))

Edit:  
I tried a local, manual installation of x-pack for Logstash and this gave me success. Maybe it helps you?

Thanks, I will try a manual installation later today. Where do I copy the unzipped x-pack folder?

I have tried today to use Elasticsearch 5.1.2 with Kibana and Logstash (both 5.1.2) to avoid jar inconsistencies (switched to elasticsearch.jar (version 5.1.2) but it produces the same Exception, any suggestions?

I had the same issue. You will need to include/upgrade to the following elasticsearch client and plugin jars:

transport-5.2.0.jar  
transport-netty3-client-5.2.0.jar  
transport-netty4-client-5.2.0.jar  
reindex-client-5.2.0.jar  
percolator-client-5.2.0.jar  
lang-mustache-client-5.2.0.jar

You can find them here:

Thanks a lot, I have updated my build.gradle.

I am now getting a different exception, I think I have overseen a configuration. I also suspect that the username and password have to be set somewhere, but I am not sure where.

My connection build up in Java looks quite the same

The \_hostname and node.name is set to 127.0.0.1,

Calling [http://localhost:9200/\_nodes](http://localhost:9200/_nodes), returns

After reading a bit in the forum, I have tried several approaches but failed. It still seems so that I am not able to connect to the node via the Java API. Do you have an advice for me?

The elasticsearch.yml:

[cluster.name](http://cluster.name): elasticsearch  
transport.tcp.port: 9300  
[node.name](http://node.name): 127.0.0.1  
network.host: 127.0.0.1

May be share a sample project on GitHub?

Hi, thanks for will to help. I have uploaded my project to Github, it can be found here

[https://github.com/MarcelMorisse/ResilienceSeismograph](https://github.com/MarcelMorisse/ResilienceSeismograph)

Maybe a few words to get a quick overview. The goal of the program is to gather Bitcoin data and analyse it with statistical methods and text mining. I am using elasticsearch to gather post from reddit and analyse it. It can be found in the qualitativeAnalysis folder, the class (AbstractConnector.java) which has implemented the connection is in the dbi/elasticsearch folder. To start crawling data, I call the main method in Main.java in the textCrawler/reddit folder. Maybe a word of warning: As it is an one man project, I postponed commenting my code to after implementation 🙂

The Elasticsearch (5.2 but also 5.1.2 on another maschine) implementation is more or less untouched, I have added a user "java", password = "el4s7ic4java", the elasticsearch.yml looks like this (the bold ones are not used)

> ======================== Elasticsearch Configuration =========================

> cluster.name: elasticsearch  
> transport.tcp.port: 9300  
> node.name: 127.0.0.1  
> '#node.attr.rack: r1  
> '#path.data: /path/to/data  
> '#path.logs: /path/to/logs  
> '#bootstrap.memory\_lock: true  
> network.host: 127.0.0.1  
> '#http.port: 9200  
> '#discovery.zen.ping.unicast.hosts: ["host1", "host2"]  
> '#discovery.zen.minimum\_master\_nodes: 3  
> '#gateway.recover\_after\_nodes: 3  
> '#action.destructive\_requires\_name: true

Logstash is running with the following conf:

> input { stdin { } }  
> output {  
> elasticsearch {  
> hosts =\> ["localhost:9200"]  
> user =\> java  
> password =\> el4s7ic4java  
> }  
> stdout { codec =\> rubydebug }  
> }

Many thanks for any help  
Marcel
