Re: Connect a node in virtual machine with other nodes in physicalmachine with port forwarding
You should change your vm to bridge.

NAT with VM.
You just make sure SSH to VM without password.
But the best way is start to try it now.

Hi,
May I ask how you configured the VM? The hadoop on other machines can just access the VM guest on another machine without port forwarding? (just making sure I'm not being paranoid here :) )

Hi,
Just do it, I did it successfully.

I've tried to forward some ports and the other's physical machine can connect to my virtual machine via them, but I'm not sure if hadoop can connect to other nodes in this way. To my knowledge the port for the tasktracker is uncertain, so I can't forward a specific port for it.

Re: Connect a node in virtual machine with other nodes
inphysicalmachine with port forwarding
Posted by Chau Yee Cheung <jo...@gmail.com>.
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 :)

May I ask how you configured the VM? The hadoop on other machines can just access the VM guest on another machine without port forwarding? (just making sure I'm not being paranoid here :) )

I see. You can buy a router. And use router with your student account to login.
Your colleage will guide you.

We are using the campus network, only one IP can be assigned to one student account, so I think it's not pratical to use bridged mode. Thanks for the advice though.

You should change your vm to bridge.

NAT with VM.
You just make sure SSH to VM without password.
But the best way is start to try it now.
