Hi @Pardeep with Support's help we got rid of those alerts by adding 'misfire_grace_time':10 to APS_CONFIG in /usr/lib/python2.6/site-packages/ambari_agent/AlertSchedulerHandler.py on every node. After the update that section should read:
In this we are allowing up to 10 seconds for all tests to complete. After that restart all ambari_agents. We tried on one cluster and it worked. This is most likely fixed in Ambari-2.2 but happens in 2.1.2.
