I am using HDP 2.4 virtual machine on Azure,able to start Zeppelin service , when browse to http://<Host>:9995. Zeppeline Notebook show 'disconnected'. I tried stop & start, restart Zeppeline Notebook , still facing same issue. 9995 port is up and listening.
Appreciate help on resolving this issue.
I am wondering if the zeppelin-server daemon is up and running; it may not be started by default. Assuming you can 'ssh' into the server where zeppelin is installed, try this command to see if it is running:
ps -ef |grep zeppelin-server
You should see one or more tasks running, and at least one listed as interpreter.sh, which would be the interpreter for the notebook. Also, I believe your notebook is not connected until you select a given notebook. To make sure the interpreter is ready to load the notebook, navigate to the Interpreter tab along the top, find the "spark" interpreter, and click on the "restart" button. Wait for 5 seconds, then go back and reload the notebook to see if it is now connected. Also, try hitting the browser "reload" button to try to start the interpreter.
