Unable to start 3rd instance of Schema Registry

[SK]

After multiple attempts for last 2 days, I am still unable to start third instance.

I am using latest Confluent 2.0.1 with 3 nodes, all running Zookeeper and Kafka.
I am able to start on two but third one fails (Error msg listed below).

Versions,

Kafka version : 0.9.0.1-cp1
zookeeper.version=3.4.6-1569965, built on 02/20/2014
java.version=1.7.0_101

What is your kafkastore.connection.url configuration for the third schema registry instance? Can you try to set the kafkastore.init.timeout.ms to a larger value to see if that resolves your issue?

Thanks,

Liquan

My schema-registry.properties is,

port=8081
kafkastore.connection.url=Node.1.IP:2181,Node.2.IP:2181,Node.3.IP:2181
kafkastore.topic=_schemas
kafkastore.topic.replication.factor=3
debug=true


I have tried playing with timeout setting to no avail.
