Subject 答复: Cannot open channel to 1 at election address /172.23.34.80:3888
Date Mon, 29 Oct 2012 04:01:47 GMT
Hi.
The ip address is OK, I think.
You might need to check your firewall settings. You should open the 3888
port.


--------------
Hi there,

I try to install HBase 0.94.2 on my Hadoop 1.0.3 cluster. But, I can not
start HBase master successfully. Any help will be appreciated. It will be
great if any one can share his successful hbase-stite.xml for a real
cluster env.

After typing ./bin/start-hbase.sh, there is no error report in console.
But, after checking the Zoonkeeper lot file, I see the below exception.



2012-10-28 23:30:42,699 WARN
org.apache.zookeeper.server.quorum.QuorumCnxManager: Cannot open channel to
1 at election address /172.23.34.80:3888
java.net.ConnectException: Connection refused


Than, I run command  netstat -tulpn, and find that the port 3888 is bind on
strange address as shown below. Anybody can tell me where I put wrong
configuration parameter, which causes this?
