NoReplicaOnlineException with 0.8.1.1

[Prakash Gowri Shankor <pr...@gmail.com>]

Hi,

I am running Kafka 0.8.1.1 with one Zookeeper and one broker. I created a
partition 'test2' as below:

/kafka-topics.sh --create --zookeeper localhost:2181 --replication-factor 1
--partitions 3 --topic test2

I noticed this exception in the state-change.log. Why is this occuring ?
Should I be running more brokers if I have more than one partition ?

*Exception:*

kafka.common.NoReplicaOnlineException: No replica for partition [test2,2]
is alive. Live brokers are: [Set()], Assigned replicas are: [List(0)]
