ElasticSearch: Service start error

I’m facing some issue while start elasticsearch service using Linux command line sudo systemctl status elasticsearch.service .

In log, showing something like java.io.FileNotFoundException: /usr/share/elasticsearch/lib/tools.jar (No such file or directory)

Hi @narendral, see Troubleshoot - Open Distro Documentation

@aetter Thanks for reply.
For installation at my linux 16.04 LTS machine, I used this doc.
As per my machine installation, jvm path is: /usr/lib/jvm/java-1.11.0-openjdk-amd64/lib.
But I can’t able to see tools.jar. Is there any special command to create/place tools.jar into it?

My JAVA_HOME=/usr/lib/jvm/java-8-oracle
