Howdy all,
I recently upgraded to Kafka 0.8.2.0 and am trying to verify that
everything still works as expected. I spin up two brokers, one zk instance,
and then create a topic using
kafka-topics.sh --create --zookeeper ad-0104:2181 --topic deleteme
--partitions 2 --replication-factor 1
Then I run --describe to check if the partitions have leaders. I get
kafka-topics.sh --describe --zookeeper ad-0104:2181 --topic deleteme
Topic:deleteme PartitionCount:2 ReplicationFactor:1 Configs:
Topic: deleteme Partition: 0 Leader: 0 Replicas: 0 Isr: 0
Topic: deleteme Partition: 1 Leader: 1 Replicas: 1 Isr: 1
Finally, I run the console producer
kafka-console-producer.sh --broker-list ad-0102:9092 --topic deleteme
I get the following warning
[2015-02-08 00:36:24,244] WARN Property topic is not valid
(kafka.utils.VerifiableProperties)
and then it waits for console input. When I try to send a message I get the
following list of error messages

Clearly there's a leader, but it's throwing a LeaderNotAvailableException.
Any help here is appreciated.
Cheers,
