Subject Re: cannot build a fully distributed mode hbase instance.
Date Wed, 13 Jan 2010 00:52:43 GMT
thanks, Jean,
                  I figured out that, in the netstat's output I can see
127.0.0.1:60000, I don't know if this means it only listen on connection
request from the same machine.
                  About the hbase.master configuration, is there anything I
can use to replace it?
