Subject Re: hbase standalone cannot start master, cannot assign requested address at port 60000
Date Wed, 15 Sep 2010 17:18:28 GMT
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.

Thanks,
Michael
