I've recently upgraded to elasticsearch 2.0, I am running an elasticsearch 2.0 server and the jar is 2.0 too. But when I try to run the following code I am getting a NoNodeAvailableException
`boolean hasIndex = client.admin().indices().exists(new IndicesExistsRequest(INDEX)).actionGet().isExists();`
Here is my Transport Client builder also:
`Settings settings = Settings.settingsBuilder().put("cluster.name", "elasticsearch").build(); client = TransportClient.builder().settings(settings).build().addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("localhost"), 9300));`
Also, the cluster name is definitely elasticsearch in the elasticsearch.yml file.
Here is the stack trace:
\<05-Nov-15 17:04:04\> NoNodeAvailableException[None of the configured nodes are available: []]
