I see in the documentation ([https://www.elastic.co/guide/en/elasticsearch/reference/current/\_installation.html](https://www.elastic.co/guide/en/elasticsearch/reference/current/_installation.html)) it is recommended to use the oracle JDK version. Let me know whether we can use Open JDK instead of Oracle JDK, is there any impact of using Open JDK.

If you use OpenJDK then one of the areas to watch out for is the cacerts that it ships with. Different packages have different trusted CAs, and they're often different to the CAs shipped with the Oracle JDK.
