I'm +1 on the PR, but I strongly agree with Anand, this should not be a
warn. We should throw an exception here and fail the build. That being said,
despite it being in the vicinity of this PR, it's not the core value of the PR,
so I've created
[METRON-1306](https://issues.apache.org/jira/browse/METRON-1306) to track it.---
