unit tests on trunk and branch-2.2 were failing https://builds.apache.org/view/A-D/view/Ambari/job/Ambari-branch-2.2/156/console (look for keyword ERROR: test_getComponentLayoutValidations_sparkts_no_hive (test_stack_advisor.TestHDP23StackAdvisor) )
It seems it was introduced by https://issues.apache.org/jira/browse/AMBARI-14494 and I have reverted the change. I will keep my eyes on this to make sure it remedies the problem. -- -jun
