Please mark each with an "x"

• Opening PR against develop NOT master (OR feature-name if this is part of an ongoing feature development).
• A JIRA ticket exists (if not, please create this first)[https://issues.apache.org/jira/browse/ZEPPELIN/]
• Title of PR is "MAHOUT-XXXX Brief Description of Changes" where XXXX
  is the JIRA number.
• Assigned JIRA to self (almost forgot- thanks template!)
• Created unit tests where appropriate N/A
• Added documentation in scala docs/java docs, (and website once that
  is merged to dev) N/A
• Added licenses correct on newly added files N/A (adding license will mess up the template)
• Successfully built and ran all unit tests, verified that all tests
  pass locally. N/A Won't know this is working for sure until it is added to master.

If all of these things aren't complete, but you still feel it is
appropriate to open a PR, please add [WIP] after MAHOUT-XXXX before the
descriptions- e.g. "MAHOUT-XXXX [WIP] Description of Change"
