Starting Zeppelin server from Java client

[Fazlan Nazeem <fa...@wso2.com>]

Hi,

I tried to start Zeppelin server from java a client.  i added all the
dependent libraries to my project and tried running it, but I get the
following error.

... 29 more

Is this due to not passing necessary arguments to the ZeppelinServer.main()
function? What should be passed as arguments if so?

Also I would like to know whether the zeppelin can be added as a maven
dependency for my project. Currently I could only find the
Zeppelin-interpreter dependency in maven repo (which is outdated).

It looks like notebook directory is not exist.
Could you check if the directory ZEPPELIN_NOTEBOOK_DIR env variable or
zeppelin.notebook.dir jvm property pointing is exists?
Default directory is 'notebook' in current path.

Thanks,
moon
