Hi Kafka Users,

We are using kafka 0.8.2.1.We are not able to delete to any topic .
We are using AdminUtils to create and delete topic.
The topics get created successfully  with correct Leader and isr for each topic 
partitions.
But when we try to delete topic using AdminUtils.deleteTopic(), it fails.The 
topic is indefinitely
Marked for deletion.When I see the topic details, all partitions have Leader:-1 
and isr:{}.
For cleanup, I had to manually delete topic partitions from zk and kafka and 
restart both the process.
But since, we are going to using kafka in production, the above clean up policy 
wont work.

I have set delete.topic.enable=true.

Any Suggestions.
