Subject Re: HBase Java client - unknown host: localhost.localdomain

I think you need to post the screenshot on an external website and send the
link here.

So, you are trying to access your VM from outside of your VM? Or your
client application is into the VM too?

If you are outside of your VM, are you able to access the VM from outside?

Like, are you able to access the WebUI from outside of the VM with
something like "http://cloudera:60010"?
