Hi,

I was running my HBase-Hadoop setup just fine with HBase 0.92.0 and Hadoop
1.0.1.on 3 nodes

Recently upgraded to HBase-0.94.1 and Hadoop-1.0.3.

Since i was running a trial environment I hadnt added my machines to a DNS.
Now after the version change, the HRegionServer processes began failing
over not being able to reverse look up the IPs of my nodes.

So I got that worked out and added the servers onto the DNS. After which im
getting the foloowing SASL exceptions.

Am I missing something?

Upon start-up all the processes are up but the logs indicate "failed
construction of HMaster".

Can I disable SASL authentication?

It says at the end that the connection is refused, most likely your
zookeeper server at "10.12.19.110:2181" is not running.

Looking at your life, it seems like SASL is just.a warning/info message.. your real issue is invalid zookeeper sessions.. Can you try stopping everything, delete zookeeper data dir and data log dir and start.. Also are you running a version of zookeeper compatible with your hbase version?
