Topic missing Leader and Isr
I checked out the Kafka 0.8.2 branch and used the "./bin/kafka-topics.sh"
script to create a topic:
./bin/kafka-topics.sh -create -zookeeper zk-node:2181 -partitions 12
-replication-factor 1 -topic my-topic`
But when I use the "--describe" to look at the topic both the 'Leader' and
'Isr' are missing. Is this expected of a new/empty topic? If not how to fix
this?
Thanks!

This seems to be an issue thats fixed in 0.8.2 and after upgrading the
kafka cluster to 0.8.2 this issue was resolved.

Oh let me further add. I believe there is no leader/isr when I've
re-created a deleted topic. If I pick a topic name never seen before I get
a leader/isr. Were you deleting topics? Deleting topics is also a good
test of your system. FYI:
$KAFKA_HOME/bin/kafka-run-class.sh kafka.admin.DeleteTopicCommand
--zookeeper $ZK --topic test

Hey, not a help, but I just posted the same question. I'm noticing the
same thing. Where is your hardware? Just curious. I'm running my
kafka/zookeeper on AWS.

Also note that the metadata for the topic is missing. I tried creating few
more topics and all have the same issue.
Using the Kafka console producer on the topic, I see these error messages
indicating the missing metadata:
WARN Error while fetching metadata [{TopicMetadata for topic my-topic ->
No partition metadata for topic my-topic due to
kafka.common.UnknownException}] for topic [my-topic]: class
kafka.common.UnknownException (kafka.producer.BrokerPartitionInfo)
