Hi,
We have a Java application that connects to elasticSearch 2.4 (standalone) via Spring Data and Spring Boot (1.4.0). The connection settings are:
spring.data.elasticsearch.cluster-name=
spring.data.elasticsearch.cluster-nodes=127.0.0.1:9300
Everything worked fine before installing Shield.
I installed Shield on my DEV (windows) box, The GET \_shield shows status as enabled. Added more settings as below,
spring.data.elasticsearch.properties.shield.user=:
spring.data.elasticsearch.clientPingTimeout=30s
spring.data.elasticsearch.clientNodesSamplerInterval=30s
spring.data.elasticsearch.properties.request.headers.X-Found-Cluster=s
spring.data.elasticsearch.properties.shield.transport.ssl=false
however, the application failed to start due to error:
`SEVERE: failed to load elasticsearch nodes : org.elasticsearch.client.transport.NoNodeAvailableException: None of the configured nodes are available: [{#transport#-1}{127.0.0.1}{127.0.0.1:9300}]`
Does anyone have any suggestions?
Thanks in advance.

Can you curl localhost:9200 to make sure ES is up?
Have you defined any users in Shield?
[https://www.elastic.co/guide/en/shield/current/\_using\_elasticsearch\_java\_clients\_with\_shield.html](https://www.elastic.co/guide/en/shield/current/_using_elasticsearch_java_clients_with_shield.html) may also be of use.

Hi Mark,
I use Sense plugin, yes, ES is up,
GET \_shield:
"status": "enabled",
GET \_shield/authenticate:
{
"username": "\*\*\*",
"roles": [
"admin"
],
"full\_name": null,
"email": null,
"metadata": {}
}

If you have defined a user in Shield, it doesn't look like you have used that user in your code;

It seems like it is Spring data setting issue, the following key-value pair is not recognised and passed to ES:
spring.data.elasticsearch.properties.shield.user= es\_admin:\*\*\*
The following Java client works:
```
Settings settings = Settings.settingsBuilder()
.put("cluster.name", clusterName)
.put("shield.user", "es_admin:***").build();
TransportClient client = TransportClient.builder()
.addPlugin(ShieldPlugin.class)
.settings(settings)
.build()
.addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("localhost"), 9300));
```
This [No Node Available with Spring Data and Shield](https://discuss.elastic.co/t/no-node-available-with-spring-data-and-shield/52003) elastic cloud topic mentioned Spring data settings, but we use standalone ES.

Error message:

INFO: adding transport node : localhost:9300

I debugged into TransportClientFactoryBean buildClient(), the value for "shield.user" was passed in.
I suspect because the buildClient method does not have `.addPlugin(ShieldPlugin.class)`, hence the shield user credentials were NOT passed to ES.
org.springframework.data.elasticsearch.client.TransportClientFactoryBean spring-data-elasticsearch:2.0.2.RELEASE

Overriding default TransportClientFactoryBean made it work.
There is a Spring Data Elasticsearch Jira ticket for this [Add plugins management on TransportClientFactoryBean](https://jira.spring.io/browse/DATAES-310)
