Subject [Hadoop Wiki] Update of "BindException" by SteveLoughran
Date Mon, 26 Oct 2015 11:07:46 GMT
Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Hadoop Wiki" for change notification.

The "BindException" page has been changed by SteveLoughran:
https://wiki.apache.org/hadoop/BindException?action=diff&rev1=10&rev2=11

   * If the port number is below 1024, the OS may be preventing your program from binding
to a "trusted port"
   * 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 you are running on EC2, your service is trying to explicitly bind a public Elastic
IP address using the public hostname or IP, or implicitly using "0.0.0.0" as the 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.
