Elasticsearch indexing not working and error message: node null not part of the cluster Cluster [elasticsearch], ignoring

elasticsearch, spring-data-elasticsearch

Solution

For those who met the same error and came here from search engines, make sure the `TransportClient` is using the same cluster name as the cluster itself.

- Verify cluster name.

Visit http://localhost:9200 to check the cluster name. The default name is `elasticsearch`. If you customised the cluster name using `elasticsearch.yml` file, make sure the config file is picked up.

Set `culster.name` when creating `TransportClient`.

Settings settings = ImmutableSettings.settingsBuilder()
        .put("cluster.name", clusterName)
        .put("client.transport.ignore_cluster_name", false)
        .put("node.client", true)
        .put("client.transport.sniff", true)
        .build();
client = new TransportClient(settings).addTransportAddress(new  InetSocketTransportAddress(host, port));

Ignore cluster name check

You can ignore the check of cluster name by setting `client.transport.ignore_cluster_name` to `true`.

- Debug if the error still exists

If the error still exists, launch your application in debug mode, and debug `TransportClientNodesService`.

Problem

I just downloaded the elastic search distribution and ran it. ``` curl 'localhost:9200' { "status" : 200, "name" : "cbs", "cluster_name" : "elasticsearch", "version" : { "number" : "1.4.1", "build_hash" : "89d3241d670db65f994242c8e8383b169779e2d4", "build_timestamp" : "2014-11-26T15:49:29Z", "build_snapshot" : false, "lucene_version" : "4.10.2" }, "tagline" : "You Know, for Search" } ``` And I am trying to access it using spring-data. Added the following lines in application-context (as per spring data documentation) with xml namespace: ``` <elasticsearch:repositories base-package="com.cbs" /> <elasticsearch:transport-client id="client" cluster-nodes="127.0.0.1:9300" cluster-name="elasticsearch" /> <bean name="elasticsearchTemplate" class="org.springframework.data.elasticsearch.core.ElasticsearchTemplate"> <constructor-arg name="client" ref="client" /> </bean> ``` Here is the entity and repository code: ``` @org.springframework.data.elasticsearch.annotations.Document(indexName = "product", type = "product", shards = 1, replicas = 0, indexStoreType = "memory", refreshInterval = "-1") public class Product { @Id private String id; private String name; } @Repository public class ProductSearchDaoImpl implements IProductSearchDao { @Autowired private ElasticsearchOperations elasticsearchOperations; @Override public void index(Product product) { elasticsearchOperations.createIndex(Product.class); elasticsearchOperations.putMapping(Product.class); IndexQuery indexQuery = new IndexQueryBuilder().withId(product.getId()).withObject(product).build(); elasticsearchOperations.index(indexQuery); elasticsearchOperations.refresh(Product.class, true); } } ``` Now when I run the test case to index the product, I am getting a consistent warning message (every 2 seconds or so) as ``` [Neuronne] node null not part of the cluster Cluster [elasticsearch], ignoring... [Neuronne] node null not part of the cluster Cluster [elasticsearch], ignoring... ``` And the product is not getting indexed (even the index is not created) ``` curl 'localhost:9200/_cat/indices?v' health status index pri rep docs.count docs.deleted store.size pri.store.size ``` Can anyone help me out with this?
