Hi again, I think the hbase server master is not starting because it is attempting to open port 60000 on its public IP address, rather than using localhost. I cannot seem to figure out how to force it (well, configure it) to attempt to bind to localhost:60000 instead. As far as I can see, this is set in the file:
org/apache/hadoop/hbase/master/HMaster.java I don't know much about java, so I'd prefer not to edit the source if there is an option, but I will if necessary. Can someone please point me to the way to change this setting? Any help would be greatly appreciated.
