Hey Jason. Thanks for trying hbase.
Can you take a look at your networking? Remote regionservers are
reporting in as 127.0.1.1:60020 rather than as 10.211.55.X.
The master keeps an in-memory Map of all regionservers. The key is the
regionserver's reported Address+Port. If all are reporting in as
127.0.1.1:60020, then the master is confused (AssertionError).
Yours,
St.Ack
P.S. Would suggest you also use the latest release candidate:
http://people.apache.org/~stack/hbase-0.1.2-candidate-1/. It is much
improved over 0.1.1.

Hi
I am very new to hbase and have just set it up for the first time. I
have a running hadoop cluster with 5 datanodes and have installed
HRegionServers on each of these nodes.
When I start up hbase I see this error in the master log:-
