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

             Summary: Added MR2 properties were not added to host with MR2 clients, but without MR2 master
                 Key: AMBARI-3027
                 URL: https://issues.apache.org/jira/browse/AMBARI-3027
             Project: Ambari
          Issue Type: Bug
          Components: controller
    Affects Versions: 1.4.0
            Reporter: Sumit Mohanty
            Assignee: Sumit Mohanty
             Fix For: 1.4.0


Steps:
# During cluster installation, go to "Customize Services" page -> "MapReduce 2" tab.
# Add property "x".
# Continue installation.
Property "x" was added to file /etc/hadoop/conf/mapred-site.xml for all hosts with MR2 client.

# Stop MR2.
# Add property "y".
# Save changing.
# Start MR2.

Result:
Property "y" was added to file /etc/hadoop/conf/mapred-site.xml for host  with MR2 master, but was not for hosts only with MR2 clients.
Also, if you delete "x" property after installation, it will be deleted from host with MR2 master and will be still on hosts with MR2 clients only.
