Subject Re: Zookeeper tries to connect to localhost when i have specified another clearly.
Date Wed, 21 Aug 2013 13:00:26 GMT
All fine on those logs too.

So everything is working fine, ZK, HBase, the job is working fine too. The
only issue is this INFO regarding SAS, correct?

I think you should simply ignore it.

If it's annoying you, just turn org.apache.zookeeper.ClientCnxn loglevel to
WARN on log4j.properties. (It's the setting I have on my own cluster).
