----------------------------------
Summary: Need some logging when JSON parsing throws an error
Key: AMBARI-5574
URL: https://issues.apache.org/jira/browse/AMBARI-5574
Project: Ambari
Issue Type: Bug
Components: agent
Affects Versions: 1.6.0
Reporter: Dmytro Sen
Assignee: Dmytro Sen
Fix For: 1.6.0
We have had some reports of Agent-Server communication going down because of
JSON parsing error. This is usually a malformed JSON that either the agent
sends or receives. We need some WARN level log to spit out the JSON when such
error is encountered.
The possibility is that the Agent logs the last JSON sent to the server when it
encounters a communication error with the server. And, similarly, it can log
the JSON received if response processing encounters an error. At Controller.py,
the heartbeat loop we can log response or data or both based on when the
failure occurs.
