Hi all, The work to migrate the very outdated Bootstrap 2 (originally used for Ambari back in 2012) to Bootstrap 3 has been done via https://issues.apache.org/jira/browse/AMBARI-18573.
This is mostly library, CSS class names, and some markup changes, with a small amount of refactoring. Just a heads up that the plan is to commit this by tomorrow (Oct 14) around 12PM Pacific. Thanks, Aleks
