Apache Zeppelin 0.7.3 - http error 503 in browser
The workaround was:
Install Java 8, following How to set or change the default Java (JDK) version on OS X?, i.e.
brew tap caskroom/versions brew cask install java8 export JAVA_HOME=`/usr/libexec/java_home -v 1.8`
Then:
sudo bash zeppelin-daemon.sh start /Applications/Safari.app/Contents/MacOS/Safari

http://localhost:8080

Zeppelin 0.7.3 only supports Java <= 8.0
zeppelin-daemon.sh must be run as root, but browser doesn't have to be
