Opendistro Elasticsearch on startup

General Feedback
1

Hi,

I’ve installed on Ubuntu 18.04 LTS, and dutifully gone through ALL steps. Then sudo systemctl start elasticsearch.service

On startup of the service I am receiving

java.security.policy: error adding Entry:
java.net.MalformedException: unknown protocol: jrt

and cannot subsequently connect to the instance.

JAVA_HOME is pointing to /usr/lib/jvm/java-11-openjdk-amd64 directory

This machine previously had the standard ES install on it, and this was removed.

Would appreciate any pointers to this error…

Update: The service IS running, but when I run netstat -a -n nothing is listening to port 9200.

The elasticsearch.yml file is default

I have also tried changing network.host to 0.0.0.0, and also as 127.0.0.1, but made no difference.
