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

             Summary: Ambari agent lost heart beat because of inconsistency in blueprint tables
                 Key: AMBARI-19929
                 URL: https://issues.apache.org/jira/browse/AMBARI-19929
             Project: Ambari
          Issue Type: Bug
          Components: ambari-server
    Affects Versions: 2.2.1
            Reporter: amarnathreddy
            Priority: Critical


If there is any inconsistency with topology_logical_request, topology_request tables then
all heart beat request fails with below exception

10 Jan 2017 10:43:12,004  WARN [qtp-ambari-agent-137] ServletHandler:563 - /agent/v1/register/agent540.xxxx.com
java.lang.NullPointerException

some of the entries for topology_request does not have reference entry in topology_logical_request
table.
because of that all healthy agents are marked as heart beat lost.
This should not happen, rather it should print the exception and process the heart beats.
