-------------------------------------

Seems Something invalid :

Rack: /ns0/default-rack
   127.0.0.1:33699 (localhost)
   127.0.0.1:37965 (localhost)

   127.0.0.1:44011 (localhost)
   127.0.0.1:46833 (localhost)

Rack: /ns1/default-rack
   127.0.0.1:34369 (localhost)
   127.0.0.1:35535 (localhost)

   127.0.0.1:43407 (localhost)
   127.0.0.1:43881 (localhost)
{noformat}

Tried the scenario, Gave an output like this, Same as the asked behavior.

[~elgoiri] Guess we can close this as Not a Problem?
