Just a heads up to the dev list that a couple PRs on the Kerberos docs resulted in a bad merge that pushed some new instructions and formatting changes to the wrong place. I'm working on a fix now - https://issues.apache.org/jira/browse/METRON-899
If you are running the Ambari Kerberos install now, it's best to reference the previous commit for those docs - https://github.com/apache/incubator-metron/blob/41b5b1050cf29e5dcb5d0c36b5a9dbd1cafa745e/metron-deployment/vagrant/Kerberos-setup.md until the fix gets merged. Best, Mike
