> 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
> Priority: Minor
>
> 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.
