The "BindException" page has been changed by SteveLoughran: https://wiki.apache.org/hadoop/BindException?action=diff&rev1=8&rev2=9 Comment: more on port:0 binding * If the configuration is a {{{hostname:port}}} value, it may be that the hostname is wrong -or its IP address isn't one your machine has. * There is an instance of the service already running. - 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. + 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. As you cannot have more than one process listening on a TCP port, whatever is listening is stopping the service coming up. You will need to track down and stop that process, or change the service you are trying to start up to listen to a different port.
