Do you see any error in "Zeppelin" server log? Pleas share the log snippet. As you are getting 503 (5xx-internal server error) so definitely looking at the log will be useful. We must see an error there explaining the cause of the failure.

Sometimes it happens due to corrupted "interpreter.json" Please verify the same, Else if possible then try reinstalling zeppelin to restore interpreter.json

Also please check if the permissions for the zeppelin is fine or not.

# chmod -R zeppelin:zeppelin /usr/hdp/current/zeppelin-server/notebook

.

Also When you try to start the Zeppelin server do you see any additional ERROR/WARNING message prior to the "unavailable" Warn message?

There's another file called zeppelin-**.out under log folder, you can check this file for the root cause.
