             Summary: check port availability when starts kylin instance
                 Key: KYLIN-3697
                 URL: https://issues.apache.org/jira/browse/KYLIN-3697
             Project: Kylin
          Issue Type: Bug
    Affects Versions: v2.5.1
            Reporter: May Zhou


As I ran the script and it turned out with no error message, and I ran the kylin.sh start script, the console output indicated that a kylin instance had successfully started, but when I visit the <host>:<port>/kylin, I found another service was running rather than kylin.
  
  I can only find the error message in the kylin.out, which is not so user-friendly.
> Caused by: java.net.BindException: Address already in use (Bind failed)
	at java.net.PlainSocketImpl.socketBind(Native Method)
	at java.net.AbstractPlainSocketImpl.bind(AbstractPlainSocketImpl.java:387)
	at java.net.ServerSocket.bind(ServerSocket.java:375)


I am wondering why check-env does not check the availability of port, and the error message could be threw out more user-friendly.
