I am trying to use the Java Node Client and connect to a separate local elasticsearch node, running in a separate JVM. I get the following error when trying to follow the examples provided in the docs ([https://www.elastic.co/guide/en/elasticsearch/client/java-api/current/node-client.html](https://www.elastic.co/guide/en/elasticsearch/client/java-api/current/node-client.html)).

Code:

```
Node node = NodeBuilder.nodeBuilder()
        .client(true)
        .local(false)
        .settings(Settings.settingsBuilder().put("cluster.name", ES_CLUSTER_NAME))
        .node();

```

Error:

> Exception in thread "main" java.lang.IllegalStateException: path.home is not configured  
> at org.elasticsearch.env.Environment.(Environment.java:99)  
> at org.elasticsearch.node.internal.InternalSettingsPreparer.prepareEnvironment(InternalSettingsPreparer.java:82)  
> at org.elasticsearch.node.Node.(Node.java:128)  
> at org.elasticsearch.node.NodeBuilder.build(NodeBuilder.java:145)  
> at org.elasticsearch.node.NodeBuilder.node(NodeBuilder.java:152)

I could obviously add a "path.home" to the settings, but I just don't see this documented anywhere - so what should the value be, and why do I need to set it?

thanks!

`path.home` is documented at [https://www.elastic.co/guide/en/elasticsearch/reference/current/setup-dir-layout.html](https://www.elastic.co/guide/en/elasticsearch/reference/current/setup-dir-layout.html)

A client node is a real node, in contrast to a transport client.

You need to pass `path.home` to a node so it knows where to lookup configuration files or a place to write logs or save cluster state data .

Thanks for the reply.

For those others that might be hitting this error... I'm running a simple Java program from eclipse. In the launch profile I added:

```
-Des.path.home=/myproject/path

```

Since I save the launch file to be shared by the other developers on the team, I use an eclipse variable as the path.

```
-Des.path.home=${project_loc:/ElasticLoader}
```

I tried running from eclipse by setting -Des.path.home=/myproject/path in VM arguments in Run configuration, but i am still facing the issue
