Bugs: AMBARI-15333

Repository: ambari


When Host Check is run during cluster install, in Step 3 of the Installation 
wizard, if you click on "Click here to see the warnings" and expand User 
Issues, the message displayed incorrectly shows that a user exists on multiple 
hosts (see attachment) instead of listing the service users that exist on the 


  ambari-web/app/controllers/wizard/step3_controller.js 19ddd20 
  ambari-web/test/controllers/wizard/step3_test.js dbfb868

The issue seems to happen during parsing of the Host check warnings. In 
parseHostCheckWarnings, the warningCategories.usersWarnings array elements are 
accessed based on user.userName which is not a property of the existingUsers 
objects. Fix is to use user.name instead.

Manual testing.
mvn test

Updated test cases accordingly.
