HBase Error - assignment of -ROOT- failure

[Nightie Wolfi <ni...@gmail.com>]

Hi everyone,

I've just installing hadoop and hbase from cloudera (3) but when I try to go
to http://localhost:60010 it just sits there continually loading.

I can get to the regionserver fine - http://localhost:60030... Looking at
the master hbase server logs I can see the following log output below.

Looks like a problem with the root region.

All of this is installed on a ext4 1TB partition running Ubuntu (Natty) 11.
No cluster/other boxes).
Any help would be greatly appreciated!

This thing is driving me crazy...

Sorry.  I lost context.  What is the issue?  If I search the mailing
list I see you had issues w/ versions.  Is this what you are asking
about?

Master is trying to assign region but its getting connection refused
trying to assign the region to localhost,60020.  Is the RegionServer
running on localhost?  If not, its likely the naming needs fixin on
your hosts.

P.S. Don't go crazy.

In case you are trying it on a virtual machine.
I changed my networking options from NAT to Bridged 
and it started working. 
I am guessing it has problems accessing the network interface otherwise maybe.
