Hi All,

I have problem when deploying my elasticsearch application into application server.  
I'm using:  
-spring-data-jest [2.3.1.RELEASE]  
-Wildfly 9 as application server  
-Amazon Elasticsearch Service [using Elasticsearch versions 2.3]  
Here's the exception [https://gist.github.com/bluething/bed0b932059f812fe59f9bf2b27a1500](https://gist.github.com/bluething/bed0b932059f812fe59f9bf2b27a1500)  
That exception occur when I deploy to Wildfly. After I googling probably because file under path-home directory still being use by the service, because my Wildfly using hot deployment probably the file still locked.  
Here's my elasticsearch xml config [https://gist.github.com/bluething/3cdee2544fbea6939b4effb068a446e6](https://gist.github.com/bluething/3cdee2544fbea6939b4effb068a446e6)

My question:

1. Is it safe to delete path-home dir for node-client config?  
I want to delete that folder (and sub folder) before deployment.

2. If deleting path-home dir is not a good idea, what should I do to solve this problem? I can't change deployment process because need more resource to do it.

3. I don't use any local node, just want to connect to external node (aws service). Why I must set path-home value? Is there any way to delete it from xml config?

Embedding an elasticsearch node is not supported.

```

A TransportClient should be used instead as explained at [https://www.elastic.co/guide/en/elasticsearch/client/java-api/current/client-connected-to-client-node.html](https://www.elastic.co/guide/en/elasticsearch/client/java-api/current/client-connected-to-client-node.html)  
Or a REST Client connected directly to the Client Node as well.

The Client Node is not an embedded Node Client.

I'm not sure what you need to do here but I believe this is the cause of your problem.
