This issue is due to running the service from /opt that should not be done since both should be in separated directories.
Config directory is located in /opt/HP/HP_ALM_SERVER/
Deployment directory is located in /var/opt/HP/ALM/
Service by default should be running from /var, not /opt.
The Jetty is compressed in the configuration directory(/opt/HP/HP_ALM_Server), and is expanded and run the web app from /var/opt/HP/ALM/
