Elasticsearch - No node available

I'm getting this error for a few hours.. I'm using Play 2.2.0 and Elasticsearch 0.90.7!

Can anyone help me?

Usually the error you are getting means that your client cannot connect to the elasticsearch node(s).

  • Check that you are passing the correct parameters to your client
  • Check that you do not have issues with a firewall
  • Provide a bit more info on your situation as Nick said above, e.g. do you deploy your elastic search on a node on a cloud infrastructure like azure? In this case for example your client might time out because it cannot ping the nodes.

and you can also check some other similar cases in here, e.g. No Node Available Exception

In my case, client refused to connect to ES with this exception because cluster name on server was different then specified on client side. Client connects to ES, looks for desired cluster name, and then fails saying no node available. But in reality, that should mean that no node belongs to cluster with name specified on client side.

That can by fixed either by specifying a correct cluster name, or by setting client.transport.ignore_cluster_name to true.

I suggest you to try these settings of ES

client.transport.sniff=true
sniffOnConnectionFault=true

Are you closing off your connections? It could be you're firing stuff off to ElasticSearch, but not closing down your connections. Eventually ES will have "No nodes available"

try{
  Client client //set it up
  client.prepareSearch //do something
}

finally {
  client.close(); //close it down
}
