Supported platforms

edit

The matrix of officially supported operating systems and JVMs is available here: Support Matrix. Elasticsearch is tested on the listed platforms, but it is possible that it will work on other platforms too.

Java (JVM) Version

edit

Elasticsearch is built using Java, and requires at least Java 8 in order to run. Only Oracle’s Java and the OpenJDK are supported. The same JVM version should be used on all Elasticsearch nodes and clients.

We recommend installing Java version 1.8.0_131 or later. Elasticsearch will refuse to start if a known-bad version of Java is used.

The version of Java that Elasticsearch will use can be configured by setting the JAVA_HOME environment variable.

Elasticsearch ships with default configuration for running Elasticsearch on 64-bit server JVMs. If you are using a 32-bit client JVM, you must remove -server from jvm.options and if you are using any 32-bit JVM you should reconfigure the thread stack size from -Xss1m to -Xss320k.
