Following the minimalist installation instructions from here, then on macOS High Sierra 10.13.1 executing:

bin/zeppelin-daemon.sh start

The daemon starts OK, but pointing any browser to http://localhost:8080 yields

HTTP ERROR: 503
    Problem accessing /. Reason:

    Service Unavailable
Powered by Jetty://

The same thing happens if I run as root, or if I run the browser as root, or if I install via homebrew (brew install apache-zeppelin).

Permissions problem?

What is a solution?

Thanks!

  • I got the same Zeppelin error after upgrading from ubuntu 16.04 to 18.04. It turned out Oracle JDK 8 had been blatted with openjdk. Reinstalling Oracle JDK 8 fixed it. – snark Sep 07 '18 at 10:56

The workaround was:

  1. 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`

  2. Then:

    sudo bash
zeppelin-daemon.sh start
/Applications/Safari.app/Contents/MacOS/Safari

  3. Point browser to: http://localhost:8080

Success! Conclusions:

  1. Zeppelin 0.7.3 only supports Java <= 8.0

  2. zeppelin-daemon.sh must be run as root, but browser doesn't have to be

  • macOS 10.13.3, Zeppelin 0.7.3. Unfortunately your workaround does not work for me. – thenaturalist Feb 27 '18 at 09:50
  • @thenaturalist Thanks for the info - in the absence of any other input here, is the only different between our setups 10.13.1 vs 10.13.3 then? – jtlz2 Feb 27 '18 at 10:31

    @jitz2 not sure what led to the hickup. Initially seemed so. Completely deleted Java off my machine and installed again after reboot & followed the steps you described and now it works. In any case props to you for figuring out Java 8 & root! – thenaturalist Feb 27 '18 at 15:01

    I had a same error code with Zeppelin. After installing Java 1.8 with Brew and setting java home like above, I re-installed Zeppelin but with brew as `brew install apache-zeppelin` . Now it's working for me. – sparkonhdfs Feb 27 '18 at 22:55

  1. Install Java 1.8 as mentioned in the above post.

  2. If we can give the super user password at the time of installing, we do not have to run as root every time. See below for the logs and the option to give password.

Get the process info on the port you are using the Zeppelin server

1)sudo netstat -anp|grep 8080

2)sudo kill (ProcessID)

3)/zeppelin-server/bin/zeppelin-daemon.sh restart

This might help you
