Re: zookeeper-3.2.2:Cannot open channel to X at election address / Connection refused
The cases where we've seen this reported in the past the user tracked the issue down to a firewall problem, I'm not sure what the issue is here given you've verified that's not the problem. The log is clearly saying: > Thread:quorumcnxmana...@336] - Cannot open channel to 2 at election > address /192.168.1.3:3888 <http://192.168.1.3:3888> > java.net.ConnectException: Connection refused which means that the server is attempting to open a connection to 192.168.1.3 port 3888, but the server at that ip/port is not accepting the connection. Are you sure that both servers are up/running at the same time? The log that you included, this was for server 1 right (192.168.1.2)? You might use "netstat -a" to verify that each server is bound to the correct ports on each host, then take a look at the logs to see if this connection refused is still happening (it can happen in the logs if server 1 starts but server 2 is not yet started, but then should rectify once both servers are bound and accepting connections). If you still have issues create a jira, attach both configs and both log files and we'll take closer look. https://issues.apache.org/jira/browse/ZOOKEEPER Good Luck, Patrick On 05/10/2010 08:07 PM, chen peng wrote: > *Thank <http://www.iciba.com/thank/> you <http://www.iciba.com/you/> for > your <http://www.iciba.com/your/> kind reply,but i think port(s) works > well, it **is not <http://www.iciba.com/not/> a problem > <http://www.iciba.com/problem/>, **Any other > <http://www.iciba.com/other/> suggestions?* > PS:*In that case,i installed zookeeper-3.2.2 but hbase.* > > ---------------- > From: chenpeng0...@hotmail.com > To: phu...@gmail.com > Subject: RE: zookeeper-3.2.2:Cannot open channel to X at election > address / Connection refused > Date: Mon, 10 May 2010 14:30:55 + > > *Thank <http://www.iciba.com/thank/> you <http://www.iciba.com/you/> for > your <http://www.iciba.com/your/> kind reply,but i think port(s) works > well, it **is not <http://www.iciba.com/not/> a problem > <http://www.iciba.com/problem/>, **Any other > <http://www.iciba.com/other/> suggestions?* > PS:*In that case,i installed zookeeper-3.2.2 but hbase.* > > ------------ > Date: Sat, 8 May 2010 22:43:34 -0700 > Subject: Re: zookeeper-3.2.2:Cannot open channel to X at election > address / Connection refused > From: phu...@gmail.com > To: zookeeper-user@hadoop.apache.org; chenpeng0...@hotmail.com > > Often this is related to the port(s) being blocked by a firewall. > Perhaps you could check this (2888/3888) in both directions?

Often this is related to the port(s) being blocked by a firewall. Perhaps you could check this (2888/3888) in both directions?
