No node available problem


(rayal126) #1

I am a beginer of the elasticsearch. I came across the No node available problem and did not know how to slove it. I have set up a node in my computer and closed the firewall.

My code of the TransportClient:
Settings settings = ImmutableSettings.settingsBuilder()
.put("cluster.name", clusterName).put("client.transport.sniff", true).build();
client = new TransportClient(settings).addTransportAddress(
new InetSocketTransportAddress("localhost", 9200));

SearchResponse response = client.prepareSearch("goods")
.setSearchType(SearchType.DFS_QUERY_THEN_FETCH)
.setQuery(textQuery).setFrom(0).setSize(60).setExplain(true)
.execute().actionGet();

The error message:
Exception in thread "main" org.elasticsearch.client.transport.NoNodeAvailableException: No node available
