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.
