Review request for Ambari and Dmitro Lisnichenko.


Bugs: AMBARI-8333
    https://issues.apache.org/jira/browse/AMBARI-8333


Repository: ambari


Description
-------

STR:  
1\. Start ambari-agent  
2\. Make sure it's registered with ambari-server.  
3\. Execute ambari-agent restart

    
    
    root@u1201:~# ambari-agent restart
    Restarting ambari-agent

    ERROR: ambari-agent start failed. For more details, see /var/log/ambari-agent/ambari-agent.out:
    ====================
    Failed to start ping port listener of: Could not open port 8670 because port already used
by another process:
    UID        PID  PPID  C STIME TTY          TIME CMD
    root      9186  8274  0 11:24 pts/0    00:00:00 apt-cache showpkg iso-codes
    ====================
    Agent out at: /var/log/ambari-agent/ambari-agent.out
    Agent log at: /var/log/ambari-agent/ambari-agent.log
    

The reason for this, is that we don't kill child processes, when killing
ambari-agent, during restart.
