-------------------------------------
Not sure how RegExp fare in Java, but we could try that here if perf isn't a
big issue.
> Notify user correctly of NN and JT hostname validity

> When value provided for JT and/or NN is malformed (incorrect
> scheme://hostname:port syntax), we throw the following error:
> 'Jobtracker/namenode not in whitelist.'
> This is misleading to the user. We should let the user know that the input
> for those is malformed and the hostname:port syntax needs to be corrected.
> Above doesn't (and shouldn't) affect the tallying of those values against the
> respective white lists.
