`ES_JAVA_HOME`::
Set a custom Java path to be used.
`ES_PATH_CONF`::
Configuration file directory (which needs to include `elasticsearch.yml`,
`jvm.options`, and `log4j2.properties` files); defaults to
`/etc/elasticsearch`.
`CLI_JAVA_OPTS`::
Any additional JVM system properties you may want to apply.
`RESTART_ON_UPGRADE`::
Configure restart on package upgrade, defaults to `false`. This means you
will have to restart your Elasticsearch instance after installing a
package manually. The reason for this is to ensure, that upgrades in a
cluster do not result in a continuous shard reallocation resulting in high
network traffic and reducing the response times of your cluster.
