Hi
I am following this guide (http://zeppelin.apache.org/download.html
<http://zeppelin.apache.org/download.html>) to install Zeppelin, but wasn't
able to configure it and get it to work. I used the binary package (the one
that I don't need to compile anymore).
I would like to have Zeppelin setup as a separate server but really have no
idea what the requirement of this would be.
I have a Spark (1.5) standalone cluster setup.
The error I get from my Zeppelin interpreter log when trying to run a simple
%md command is the following:
