Subject Zookeeper error: Cannot open channel to X at election address
Date Sat, 20 Jun 2015 05:22:09 GMT
I have installed zookeeper in 3 different aws servers. The following is the configuration in
all the servers

tickTime=2000
initLimit=10
syncLimit=5
dataDir=/var/zookeeper
clientPort=2181
server.1=x.x.x.x:2888:3888
server.2=x.x.x.x:2888:3888
server.3=x.x.x.x:2888:3888
All the three instance have a myid file at var/zookeeper with appropriate id in it. All the
three servers have all ports open from the aws console. But when I run the zookeeper server,
I get the following error in all the instances.
