I have one physical server and I work only on it (no other servers). At this server I have running elastic 1.4.2 - I use this version as this is the last version elastic osgi bundle is ready for. Also at this server I have glassfish 4.1 as java-ee server. I run elastic node client inside my java-ee application. And I do it this way: > Node node = nodeBuilder().local(true).clusterName("elasticsearch").node();Client client = node.client();GetResponse getResponse = client.prepareGet("my.index-0.2.2", "post", "1").execute().actionGet();Map\ source = getResponse.getSource();System.out.println("------------------------------");System.out.println("Index: " + getResponse.getIndex());System.out.println("Type: " + getResponse.getType());System.out.println("Id: " + getResponse.getId());System.out.println("Version: " + getResponse.getVersion());System.out.println(source); > > In log I see the following: [2015-03-17T12:57:44.447+0400] [glassfish 4.1] [INFO] [org.elasticsearch.discovery] [tid: \_ThreadID=30 \_ThreadName=http-listener-1(1)] [timeMillis: 1426582664447] [levelValue: 800] [[[Pistol] elasticsearch/SCKIrGHQTaC5eEYmYfZ0Iw]] [2015-03-17T12:57:44.449+0400] [glassfish 4.1] [INFO] [org.elasticsearch.cluster.service] [tid: \_ThreadID=128 \_ThreadName=elasticsearch[Pistol][clusterService#updateTask][T#1]] [timeMillis: 1426582664449] [levelValue: 800] [[[Pistol] master {new [Pistol][SCKIrGHQTaC5eEYmYfZ0Iw][[webserver1.com](http://webserver1.com)][local[1]]{local=true}}, removed {[Pistol][uwaWFb6KTy2Sdoc8TNwdSQ][[webserver1.com](http://webserver1.com)][local[1]]{local=true},}, reason: local-disco-initial\_connect(master)]] [2015-03-17T12:57:44.502+0400] [glassfish 4.1] [INFO] [org.elasticsearch.http] [tid: \_ThreadID=30 \_ThreadName=http-listener-1(1)] [timeMillis: 1426582664502] [levelValue: 800] [[[Pistol] bound\_address {inet[/0:0:0:0:0:0:0:0:9202]}, publish\_address {inet[/SERVER IP:9202]}]] [2015-03-17T12:57:44.502+0400] [glassfish 4.1] [INFO] [org.elasticsearch.node] [tid: \_ThreadID=30 \_ThreadName=http-listener-1(1)] [timeMillis: 1426582664502] [levelValue: 800] [[[Pistol] started]] and I the this exeption: ... ``` Caused by: org.elasticsearch.indices.IndexMissingException: [my.index-0.2.2] missing at org.elasticsearch.cluster.metadata.MetaData.concreteIndices(MetaData.java:768) at org.elasticsearch.cluster.metadata.MetaData.concreteIndices(MetaData.java:691) at org.elasticsearch.cluster.metadata.MetaData.concreteSingleIndex(MetaData.java:748) at org.elasticsearch.action.support.single.shard.TransportShardSingleOperationAction$AsyncSingleAction.(TransportShardSingleOperationAction.java:139) at org.elasticsearch.action.support.single.shard.TransportShardSingleOperationAction$AsyncSingleAction.(TransportShardSingleOperationAction.java:116) at org.elasticsearch.action.support.single.shard.TransportShardSingleOperationAction.doExecute(TransportShardSingleOperationAction.java:89) at org.elasticsearch.action.support.single.shard.TransportShardSingleOperationAction.doExecute(TransportShardSingleOperationAction.java:55) at org.elasticsearch.action.support.TransportAction.execute(TransportAction.java:75) at org.elasticsearch.client.node.NodeClient.execute(NodeClient.java:98) at org.elasticsearch.client.support.AbstractClient.get(AbstractClient.java:193) at org.elasticsearch.action.get.GetRequestBuilder.doExecute(GetRequestBuilder.java:201) at org.elasticsearch.action.ActionRequestBuilder.execute(ActionRequestBuilder.java:91) at org.elasticsearch.action.ActionRequestBuilder.execute(ActionRequestBuilder.java:65) ``` So it can't find the index - my.index-0.2.2. However this index exists! Besides, when I do curl -XGET '[http://localhost:9200/\_cluster/state?pretty=1](http://localhost:9200/_cluster/state?pretty=1)' I see there only one node and this _is not_ SCKIrGHQTaC5eEYmYfZ0Iw. I suppose that the node I create using java API creates new cluster and dosn't connect to my existing cluster - that's why it says - it's master. Or I don't understand something I have problem with code. Besides I've checked tha name of cluster it's elasticsearch. So, how can I connect to my existing elasticsearch cluster? -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
