Problem binding to [bigdata-server-01:9000] java.net.BindException: Cannot assign requested address;

 

If the port is "0", then the OS is looking for any free port -so the port-in-use and port-below-1024 problems are highly unlikely to be the cause of the problem. Hostname confusion and network setup are the likely causes.
