具有Play 2配置的ElasticSearch

Question

I am trying to use the ElasticSearch module ( https://github.com/cleverage/play2-elasticsearch ) with my Play 2 application. In the readme, it says I should add the following to my application.conf:

    ## define local mode or not
elasticsearch.local=false

## list clients
elasticsearch.client="192.168.0.46:9300"
# ex : elasticsearch.client="192.168.0.46:9300,192.168.0.47:9300"

What is local mode? What is my client URL supposed to be? I can not find any information on what these options should be. With my current options, I get a NoNodeAvailableException.

Some people suggest:

elasticsearch.local=false elasticsearch.client=mynode1:9200,mynode2:9200

But what is mynode1 and mynode2? It doesn't work with my application. Can anyone help? Thanks

Answer 1

What is local mode?

If elaticsearch.local=true, a elasticsearch node is started in your application ( embedded )

What is my client URL supposed to be?

It's your host:port, but the port is the tcp transport define on your elasticsearch node. By default, the port start on 9300 ( http://www.elasticsearch.org/guide/reference/modules/transport.html )

I can not find any information on what these options should be. With my current options, I get a NoNodeAvailableException.

I think you have a problem on port number.

Answer 2

mynode1 and mynode2 are elasticsearch nodes.

Do you have any Elasticsearch node running? On which IP address?

Can you try to connect on these nodes using curl, for example:

curl localhost:9200

Or

curl YOURIPADDRESS:9200

If one of this is successful, then configure your play app using YOURIPADDRESS:9300 as Nicolas Boire wrote before. If no one is successful, check that you have installed Elasticsearch and launched it before.

I've just had the same problem, be sure that you respect the version requirements written in the table : https://github.com/cleverage/play2-elasticsearch

At the beginning, I set up the latest version of the plugin 0.8.1 but my ElasticSearch version was 1.0.2 . By starting ES with version 0.9.13 , it worked.
