             Summary: 'Percent NodeManager Live' alert and 'Percent NodeManager healthy' alert
for YARN service work with a considerable delay
                 Key: AMBARI-3256
                 URL: https://issues.apache.org/jira/browse/AMBARI-3256
             Project: Ambari
          Issue Type: Bug
            Reporter: Andrew Onischuk
            Assignee: Andrew Onischuk
             Fix For: 1.4.1


1. Stop a NodeManager. 
*Actual result:*
2. Two alerts for the NodeManager appear quite soon on the corresponding Host Details page
and on the Hosts page. 
3. No alerts present on the ServicesPage->Yarn for at least 10 min. Same is true for Dashboard->ClassicView->Yarn->NodeManagersLive.

4. 1 alert appears some considerable time later. 

*Expected result:*
3. Alerts and 'NodeManagers live' counter change synchronously with 2. 
4. *1* or *2* alerts should be present *?*
