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

             Summary: Ambari agent unable to register with server when server response is
too big
                 Key: AMBARI-17991
                 URL: https://issues.apache.org/jira/browse/AMBARI-17991
             Project: Ambari
          Issue Type: Bug
          Components: ambari-server
    Affects Versions: 2.4.0
            Reporter: Dmytro Sen
            Assignee: Dmytro Sen
            Priority: Blocker
             Fix For: 2.4.0


Ambari agent is unable to register with ambari server, failing with:

{code}

INFO 2016-06-09 11:22:00,964 security.py:147 - Encountered communication error. Details: SSLError('The
read operation timed out',)
ERROR 2016-06-09 11:22:00,965 Controller.py:196 - Unable to connect to: https://localhost:8441/agent/v1/register/dvtcbdqd02.corp.cox.com
Traceback (most recent call last):
  File "/usr/lib/python2.6/site-packages/ambari_agent/Controller.py", line 150, in registerWithServer
    ret = self.sendRequest(self.registerUrl, data)
  File "/usr/lib/python2.6/site-packages/ambari_agent/Controller.py", line 423, in sendRequest
    raise IOError('Request to {0} failed due to {1}'.format(url, str(exception)))
IOError: Request to https://server1:8441/agent/v1/register/host1 failed due to Error occured
during connecting to the server: The read operation timed out
ERROR 2016-06-09 11:22:00,965 Controller.py:197 - Error:Request to https://server1:8441/agent/v1/register/host1
failed due to Error occured during connecting to the server: The read operation timed out
{code}

The problem was fixed by modifying the timeout in  /usr/lib/python2.6/site-packages/ambari_agent/security.py:

{code}
def create_connection(self):
    if self.sock:
      self.sock.close()
    logger.info("SSL Connect being called.. connecting to the server")
    sock = socket.create_connection((self.host, self.port), 120)
{code}

Use Jetty 8 instead of 9 in Ambari 2.4.0
