Je ne parviens pas à me connecter au cluster Vanilla ElasticSearch via l'API Java.
Reproduire:
#start elasticsearch
elasticsearch -f
#checking in a new window
$ curl -XPUT 'http://localhost:9200/Twitter/Tweet/1' -d '{\
"user" : "kimchy",\
"post_date" : "2009-11-15T14:12:12",\
"message" : "trying out Elastic Search"\
}'
résultat:
{
"ok": true,
"_index": "Twitter",
"_type": "Tweet",
"_id": "1",
"_version": 3
}
$ curl -XGET 'http://localhost:9200/Twitter/Tweet/_search?q=user:kimchy'
résultat:
{
"took": 2,
"timed_out": false,
"_shards": {
"total": 5,
"successful": 5,
"failed": 0
},
"hits": {
"total": 1,
"max_score": 0.30685282,
"hits": [
{
"_index": "Twitter",
"_type": "Tweet",
"_id": "1",
"_score": 0.30685282,
"_source": {
"user": "kimchy",
"post_date": "2009-11-15T14:12:12",
"message": "trying out Elastic Search"
}
}
]
}
}
Donc, tout fonctionne via HTTP. Essayer via Java (par cette page ):
public static void main(String[] args) {
Client client = new TransportClient()
.addTransportAddress(new InetSocketTransportAddress("localhost", 9200));
IndexResponse response = null;
try {
response = client.prepareIndex("Twitter", "Tweet", "1")
.setSource(XContentFactory.jsonBuilder()
.startObject()
.field("user", "john")
.field("postDate", new Date())
.field("message", "who dont it work")
.endObject()
)
.execute()
.actionGet();
} catch (ElasticSearchException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
System.out.println(response);
}
Et je reçois la trace de pile suivante:

Et la chose la plus proche que j'ai trouvée jusqu'à présent à ce problème est ici , mais le fil a traîné sans résolution.
Le port par défaut de TransportClient est 9300. Vous devez l’utiliser au lieu de 9200 dans votre code Java. C'est probablement pourquoi la connexion a échoué.
import Java.net.InetAddress;
import Java.net.UnknownHostException;

//create cliet !!!Make sure keep settings empty if your cluster is the
//same as the one you defined in your elasticsearch.yml file
//Plus, port here(9300)must be different from your http port(9200)
TransportClient client = new PreBuiltTransportClient(Settings.EMPTY)
.addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("127.0.0.1"), 9300));
//get data
GetResponse response = client.prepareGet("Twitter", "Tweet", "1").execute().actionGet();
//output
System.out.println(response.getSourceAsString());
client.close();
}
