             Summary: Ambari Agent hung when ambari server sends agent restart action
                 Key: AMBARI-26516
                 URL: https://issues.apache.org/jira/browse/AMBARI-26516
             Project: Ambari
          Issue Type: Bug
          Components: ambari-agent
    Affects Versions: 2.7.5, 3.0.0
         Environment: All Enviroments
            Reporter: Vijayakumar Govindasamy


{*}Problem{*}:

When ambari agent is not reporting to server for a period of time and tries to resume the reporting, Ambari Server requests agent auto restart action. Due to a bug in the code, Agent auto restart fails and hungs in the same state.

{*}Problematic code{*}:

Utils.py
{code:java}
def restartAgent(stop_event, graceful_stop_timeout=30):
  ExitHelper().exitcode = AGENT_AUTO_RESTART_EXIT_CODE
  stop_event.set()

  t = threading.Timer( graceful_stop_timeout, ExitHelper().exit, [AGENT_AUTO_RESTART_EXIT_CODE])
  t.start() {code}
*Fix:*
{code:java}
def restartAgent(stop_event, graceful_stop_timeout=30):
  exit_helper = ExitHelper()
  exit_helper.exitcode = AGENT_AUTO_RESTART_EXIT_CODE
  stop_event.set()

  t = threading.Timer( graceful_stop_timeout, exit_helper.exit)
  t.start() {code}
