Description

This issue affects only developers

When downloading the code from github and trying to run the tests of the project core via sbt, one will face an error stating that the METADATA configuration is missing, e.g:
[ERROR] [Storage$] Required repository (METADATA) configuration is missing.
[ERROR] [Storage$] There were 1 configuration errors. Exiting.

It looks like the project predictionio core requires a METADATA datasource (elasticsearch) installed and configured in the developer machine.

There are some benefits if the project require less external installation/configuration:

• Developers would have an easy setup of the environment.
• Continuous integration would be easier

How to reproduce:

• Download predictionio from github
• In root folder run ./make-distribution.sh
• In root folder run sbt core/test
