----------------------------------------------

Hi, we faced issue that is related with this patch. Please see AMBARI-16019. 
This is cased by two lines of code that was added in committed patch 

// Do not allow "Proceed Anyway" for validation errors
          disablePrimary: self.get('configValidationError'),

This may block users, or make them do unwanted changes to configs.

Please see patch for AMBARI-16019. The fix is simple, we remove this two lines. 

Just wanted to let you know about that changes and please put more people for 
review if you do such a fundamental changes.

> HAWQ config should not allow multiple Master/Segment directories
