Are there a special installation to install alluxio on one openstack machine ?

It looks like the Alluxio master's web UI cannot start because the address is already in use. This happens if the port is taken by another process. Alluxio web UI uses the port 19999 for the web UI by default. If you expect another process to be using that port, you can change the Alluxio master web UI port by changing the configuration parameter ( http://www.alluxio.org/docs/master/en/Configuration-Settings.html#master-configuration ), alluxio.master.web.port , to another port number.
