Subject Re: Connect a node in virtual machine with other nodes inphysicalmachine with port forwarding
Date Mon, 07 Apr 2014 16:03:35 GMT
The problem is, we live in different dormitories, so I don't know how to
use a router to make things better...

But today I went to the lab and found out that we can pick any IP if we use
the network there, though we managed to connect the machines together
without using brigded mode anyway(The other machine could start the
datanode and the tasktracker in my VM). Now we are trying to make them run
the job together(some legacy symlinks seems to get in our way)

Thanks for your advaice though :)
