Hi,all:
I have installed a cluster of 4 nodes according to the doc:
http://hadoop.apache.org/zookeeper/docs/current/zookeeperAdmin.html .My
zookeeper version is 3.3.2.
Now I have a question, my cluster always has error logs like this:
---------------------------------------
2010-12-20 12:29:52,538 WARN
org.apache.zookeeper.server.quorum.QuorumCnxManager: Cannot open channel to

------------------------------------------
And this is my iptables rules:
Chain INPUT (policy ACCEPT)
target prot opt source destination
RH-Firewall-1-INPUT all -- anywhere anywhere
Chain FORWARD (policy ACCEPT)
target prot opt source destination
RH-Firewall-1-INPUT all -- anywhere anywhere
Chain OUTPUT (policy ACCEPT)
target prot opt source destination
Chain RH-Firewall-1-INPUT (2 references)
target prot opt source destination
ACCEPT all -- anywhere anywhere
ACCEPT icmp -- anywhere anywhere icmp any
ACCEPT esp -- anywhere anywhere
ACCEPT ah -- anywhere anywhere
ACCEPT udp -- anywhere anywhere udp dpt:ipp
ACCEPT tcp -- anywhere anywhere tcp dpt:ipp
ACCEPT all -- anywhere anywhere state
RELATED,ESTABLISHED
ACCEPT tcp -- anywhere anywhere state NEW tcp
dpt:ssh
REJECT all -- anywhere anywhere reject-with
icmp-host-prohibited
What should I do to resolve the problem?
Thanks for your help very much!
