Issue -
Whenever I reboot my host server, elastic search fails to start with below error:
Aug 14 06:43:00 ********systemd: Starting Elasticsearch...

But if i create /var/run/elasticsearch and chown to elasticsearch user. Elasticsearch service starts normally a nd works fine.
Below is my init script:
