The agent is making a request to an endpoint "/ca" that does not exist on the
server.
- On the agent:
https://github.com/apache/ambari/blob/branch-2.1/ambari-agent/src/main/python/ambari_agent/NetUtil.py#L105
- On the server:
https://github.com/apache/ambari/blob/branch-2.1/ambari-server/src/main/java/org/apache/ambari/server/security/SecurityFilter.java#L75
It looks like the agent should be hitting "/cert/ca" rather than just "/ca".
However, if this request fails consistently on the server side, a) why does the
server return a 200 code, and b) what's the point of the request?
Regardless of this request failing, the agent successfully registers with the
server.
