Hi, I'm trying to install HBase 0.20.0 in fully distributed mode on my cluster. As HBase depends on Zookeeper, I have to know first how to make Zookeeper work. I download the release 3.2.1 and install it on each machine in my cluster.
Zookeeper in standalone mode works well on each machine in my cluster. I follow the "Zookeeper Getting Started Guide" and get expected output. Then I come to the "Running replicated zookeeper" On each machine in my cluster(debian-0, debian-1, debian-5), I append the following lines to zoo.cfg, and create in dataDir a "myid" which contains the server id(1 for debian-0, 2 for debian-1, 3 for debian-5). server.1=debian-0:2888:3888 server.2=debian-1:2888:3888 server.3=debian-5:2888:3888 then I start zookeeper server by "running bin/zkServer.sh start", and I got the following output: cl...@debian-0:~/zookeeper$ bin/zkServer.sh start JMX enabled by default Using config: /home/cloud/zookeeper-3.2.1/bin/../conf/zoo.cfg Starting zookeeper ...

I googled "zookeeper cannot open channel to at address" and searched in mailing list archives, but got nothing helpful. I need your help, thanks and best regards!
