I have had to fix some escaping problems to make travis happy, and it also
required some retries ....
anyhow travis is now happy:
https://travis-ci.org/nokia/zeppelin/builds/230331180
I hope this PR is addressed and we can move on.
I still wait hint from @felixcheung and @Leemoonsoo on how to proceed on
the rest.
thanks in advance
