> When the Ambari Agent's ping port is taken by old/left over ambari agent process. the Ambari agent install fails during the cluster installation time. The error message simply says Address already in use. As shown below.
> "ERROR 2015-08-14 17:11:26,557 main.py:272 - Failed to start ping port listener of: [Errno 98] Address already in use"
> The error message could have been more specific on which port was used by which process. 
> In fact, the err msg is there in the ambari-agent/src/main/python/ambari_agent/PingPortListener.py already. It's just that it was never used due to the way the awk parses the pid.
> This JIRA is to attempt to fix the awk parse cmd so that the Ambari agent python script would throw the exception with a detailed error message.
