Review request for Ambari, Srimanth Gunturi and Yusaku Sako.

Bugs: AMBARI-6328

Repository: ambari

Description (updated)

Ambari does not support ATS (Application TimeLine Server) component of YARN service in kerberized
Add Security wizard warns the user about this and deletes the ATS component as part of the
Add Service wizard on addition of any service reinstalls ATS serviceComponent and ATS serviceHostComponent.

ATS component should not be installed by the Add service wizard unless the service selected
for addition is YARN+MapReduce2.
The reason this step of installing ATS serviceComponent irrespective of the service being
added was introduced earlier because Add Service Wizard makes the POST call to create host
components for both *currently installed and selected* service's HostComponents. At this time
since ATS serviceComponent itself is not created, API call to create hostComponent for ATS
fails. We should fix this issue so that web-client just makes API POST call to create selected
service's HostComponents

  ambari-web/app/controllers/wizard/step8_controller.js 3b39f2b 
  ambari-web/app/models/service_config.js dfc480e 



Tested the patch on installer, Add Service and Add Host wizard.
