Hi,
I am trying to configure Neo4J High availability. But I am getting some
exceptions. The following are the configuration details.
We have 3 Linux servers (Amazon cloud instances).
Each one has Zookeeper 3.3.2 and Jetty 7. Deployed web application in Jetty by
giving corresponding ha-server.conf as follows:
ha.machine_id=1
ha.server=localhost:6001
ha.zoo_keeper_servers=internalip:2180, internalip:2180, internalip:2180
ha.pull_interval=5
enable_remote_shell = port=1331
Similary in linux server 2 and 3.
Configured Zookeepr as follows:
#server1.cfg
tickTime=10000
initLimit=50
syncLimit=10
dataDir=/usr/share/zookeeper-3.3.2/data/zookeeper1
clientPort=2183
server.1=ip-10-102-53-219.ec2.internal:2888:3888
server.2=ip-10-84-29-207.ec2.internal:2888:3888
server.3=ip-10-102-53-219.ec2.internal:2888:3888
Similary in linux server 2 and 3.
Now started Jetty servers and Zookeeper servers. But I am getting the following
exception at Web server Jetty servers.
[main-SendThread(ipaddtress:2180)] WARN org.apache.zookeeper.ClientCnxn -
