Subject Re: Exceptions when starting hbase
Date Thu, 24 Sep 2009 11:41:07 GMT
What I see is a fairly normal startup. It seems that it took some time
for Zookeeper to start accepting requests but then it did and the
catalog regions were assigned.

Did you have any problem using your HBase instance after it booted?
