Starting Apache Zeppelin

Starting Apache Zeppelin from the Command Line

On all unix like platforms:

After Zeppelin has started successfully, go to http://localhost:8080 with your web browser.

Stopping Zeppelin

Start Apache Zeppelin with a service manager

Note : The below description was written based on Ubuntu.

Apache Zeppelin can be auto-started as a service with an init script, using a service manager like upstart.

Yaron Ostrover

This is an example upstart script saved as /etc/init/zeppelin.confThis allows the service to be managed with commands such as

Uninstall Yarn Osx

Other service managers could use a similar approach with the upstart argument passed to the zeppelin-daemon.sh script.

Yarn Oshkosh Wisconsin

zeppelin.conf
