             Summary: Mapreduce 'Config group' changes YARN Config Group overrides and vice versa.
                 Key: AMBARI-18633
                 URL: https://issues.apache.org/jira/browse/AMBARI-18633
             Project: Ambari
          Issue Type: Bug
          Components: ambari-web
    Affects Versions: 2.2.2
            Reporter: Andrii Babiichuk
            Assignee: Andrii Babiichuk
            Priority: Blocker


*STR:*
# Change a config (Memory allocated for all YARN containers on a node) from non-default service group in YARN service and save.
# Navigate to MapReduce service and choose a non-default service group to make config changes (Map Memory) and save

*Expected Result:* MapReduce config for non-default service group should get successfully saved 
*Actual Result:* Along wth the MapReduce config changes, non-default service group of YARN that was previously tweaked gets reset to empty bag of properties.

It is noticed that while saving configs of non-default group of MapReduce service, two PUT API calls are made: one for MapReduce which is expected but one more for YARN non-default service group with empty array for desired configs.
