CI fails for unrelated changes

Looks good to me

@prabhjyotsingh if we could point what is the reason of CI failure and link to either PR or existing JIRA issue that handles it - that could help improving our infrastructure a lot

[felixcheung]

my thought would be this:

• any property needed by Zeppelin (such as to communicate with another server), it should start with "zeppelin.*"
• any property not used by Zeppelin but by a separate server or framework (eg. spark), it should start with "spark.*"
• the reason is the interpreter can then pass-through properties as-is, for example, spark interpreter can pass all "spark." property to SparkConf (and skip all the zeppelin. ones!)

I think we try to roughly follow that pattern (at least as much as I have seen)

Fair point, I'll revert this change.
