Do I have any opportunities to embed es(Elastic Search)? In another way, run it in the same JVM. And my code call use api instead of http/socket api to access es? ---

[This blog post](https://www.elastic.co/blog/elasticsearch-the-server) contains a discussion about embedding Elasticsearch 5.0. While it may be possible, it is no longer supported. ---

Do you know anyone, who did this in 5.0 successfully? ---

What is your motivation? JUnit testing? ---

No just jUnit test. I have a application focus on storage on local disk, in order to find data quickly, I write byte[] into file, and save file\_name, offset, length of the data into de es. Most important, the process of my app and the process of es is 1:1. So es is not in cluster mode, and no need in cluster mode. Now I use a network api to save data, but I think this is not efficient enough. So I look the better way to do so. Does anyone have better ideas? ---

If you don't want to do integration tests, you can just Mock ES, no? ---

You don't need to go over the network. If you want to depart from the "supported version" path, you can try something like a standalone node. I use this approach as a "mock node" for lightweight JUnit tests which run in a single JVM [https://github.com/xbib/elasticsearch-extras-client/blob/es5/src/integration-test/java/org/elasticsearch/node/MockNode.java](https://github.com/xbib/elasticsearch-extras-client/blob/es5/src/integration-test/java/org/elasticsearch/node/MockNode.java) See also [https://github.com/xbib/elasticsearch-extras-client/blob/es5/src/integration-test/java/org/xbib/elasticsearch/NodeTestBase.java#L195-L196](https://github.com/xbib/elasticsearch-extras-client/blob/es5/src/integration-test/java/org/xbib/elasticsearch/NodeTestBase.java#L195-L196) ---

I am not running in test or need mock. I want to run in product env. No cluster mode is what I need. @jprante ---

IMO if you need a 3rd party service to test your code, then it's not a unit test but an integration test, which is a different story than embedding a node. ---

Again, it is not test. Sorry for the mislead anyone thought, it for unit test. It is need in running time, use embed mode to avoid network cost. Is this clear enough? ---

I see. As @Christian_Dahlqvist said, it's not supported. As @jprante wrote, you have a workaround. ---
