Subject Re: Problem connecting to server localhost:60020
Date Fri, 17 Aug 2012 22:31:01 GMT
It looks like master is listening on 127.0.0.1. Error from one of the non-master nodes regionserver
logs:

2012-08-16 18:02:57,366 WARN org.apache.hadoop.hbase.regionserver.HRegionServer: Unable to
connect to master. Retrying. Error was:
java.net.ConnectException: Connection refused

…

And netstat:

netstat -nlpt | grep 60000
tcp6       0      0 127.0.0.1:60000         :::*                    LISTEN      -        
       


Hmm…how would I get master to listen on 0.0.0.0?

to localhost on the non-master nodes? The only reference to localhost in the config is the
ZK quorum (I couldn't find a way to use anything else).
