Hello I just Installed Elasticsearch following the official documentation on Ubuntu 16.04. Installation completed without any error. After installation, I turned on the service using the command, sudo -i service elasticsearch start. However when checking status am getting the following error:
● elasticsearch.service - Elasticsearch Loaded: loaded (/usr/lib/systemd/system/elasticsearch.service; enabled; vendo Active: failed (Result: exit-code) since Fri 2017-06-02 15:09:41 IST; 6s ago Docs: http://www.elastic.co Process: 11092 ExecStart=/usr/share/elasticsearch/bin/elasticsearch -p ${PID_D Process: 11090 ExecStartPre=/usr/share/elasticsearch/bin/elasticsearch-systemd Main PID: 11092 (code=exited, status=1/FAILURE)

There are no logs in /var/log/elasticsearch.
My configuration file is as below:
