Hi, I'm trying to figure out how to embed elasticsearch in my java/scala application. Although i found some code about the client API i'm still confused. 1 - I would like to create only one data node, and i would like it to be persistent in the sense that, each time i would start my application and give a data path it should load the data from there. I know that elasticsearch work with the disk, i just don't see from the example i red how to specify the path and all this things. 2 - Also, Can that one node be the master node and data node at the same time. Then Can i get a client out of it with node.client() ? Finally, any tutorial recommendation ? examples? Where is the javadoc, shall i generate it myself, no version online ? ---

1. You can set `path.data` to tell ES where to store and read said data. 2. Yes that is all possible. Have you looked at [https://www.elastic.co/guide/en/elasticsearch/client/java-api/current/index.html](https://www.elastic.co/guide/en/elasticsearch/client/java-api/current/index.html)? ---
