In Groovy, def esSettings = ["cluster.name":"abcd", "node.data":"false", "node.local":"false"] Server server = new ServerBuilder() .settings(ImmutableSettings.settingsBuilder() .put(esSettings) .build()) .server() My running cluster name is "elasticsearch". Now the server is not valid. In elasticsearch.log, it reported: [09:39:03,255][WARN][jgroups.UDP] discarded message from different cluster "abcd" (our cluster is "elasticsearch"). Sender was bf83ab11-03ea-b726-dc47-6cf909b2b630 How to detect the invalid server in my groovy application? Thanks. ---

Solved. After connected to the server, I just indexed one data like this: server = new ServerBuilder(). settings(ImmutableSettings.settingsBuilder().put(elasticSearchSettings).build()).server() client = server.client() try { IndexResponse response = client.index(indexRequest(" **testing**") .type(" **testings**") .id(" **testings**") .source('{" **testings**":" **testings**"}')).actionGet() } catch(Exception e) { throw new ElasticSearchException("ElasticSearch doesn't work with settings: ${elasticSearchSettings}") } println "Connected to ElasticSearch Server with settings: ${elasticSearchSettings}" ---

Its not really a matter of something that is valid or not, but I guess what you want to know is if after starting the server, has it managed to connect to some nodes. There is an API for that under the Client#admin#cluster. cheers, -shay.banon On Tue, Apr 6, 2010 at 4:55 AM, HubertChang [huixiu@gmail.com](mailto:huixiu@gmail.com) wrote: > Solved. > > After connected to the server, I just indexed one data like this: > server = new ServerBuilder(). > > settings(ImmutableSettings.settingsBuilder().put(elasticSearchSettings).build()).server() > client = server.client() > try { > IndexResponse response = client.index(indexRequest(" **testing**") > .type(" **testings**") > .id(" **testings**") > .source('{" **testings**":" **testings**"}')).actionGet() > } catch(Exception e) { > throw new ElasticSearchException("Elasticsearch doesn't work with > settings: ${elasticSearchSettings}") > } > println "Connected to Elasticsearch Server with settings: > ${elasticSearchSettings}" > > -- > View this message in context: > [http://n3.nabble.com/How-to-check-ServerBuilder-server-result-tp699252p699277.html](http://n3.nabble.com/How-to-check-ServerBuilder-server-result-tp699252p699277.html) > Sent from the Elasticsearch Users mailing list archive at [Nabble.com](http://Nabble.com). ---

In ClusterAdminClient, there is information about health and nodesinfo. In my application, the client which connect to the server has a parameter as 'cluster.name'. If 'cluster.name' has a typo mistake or other error input, the client could not persist the data. I just try to index one data with actionGet() and catch the exception. If there were some exception, the parameter specified should have some mistake. I just create a issue to address that type and field can not has the same name. It occurs when I try to index some testing data into the cluster.:). ---

You can verify that by checking if you have nodes connected... . This is similar that what you will get with trying to index a temp data (without polluting the index...). I will answer the issue. cheers, shay.banon On Tue, Apr 6, 2010 at 11:56 AM, HubertChang [huixiu@gmail.com](mailto:huixiu@gmail.com) wrote: > In ClusterAdminClient, there is information about health and nodesinfo. > > In my application, the client which connect to the server has a parameter > as > 'cluster.name'.

Yes. def nodes =client.admin().cluster().nodesInfo(new NodesInfoRequest()).actionGet().nodes() if (nodes.size() \< 2) { //process it. } Thanks. ---
