Deleted topics come back after restart

[Sebastian Schmitz <se...@propellerhead.co.nz>]

Hello,

I found that we have like 1000 topics in our dev-environment because 
many Devs create new topics for testing something. So I clean up the old 
ones, and it was all fine. However, after restarting the cluster during 
some update of the heartbeat-container, the topics are all back again.

The setting for topic.deletion is set to true and also from logs I 
checked after issuing the delete-command Kafka marked the partitions for 
deletion and then also deleted the segments list, log, offset index and 
time index.

I ran it like this: ./kafka-topics.sh --bootstrap-server localhost:9092 
--topic postman1 --delete

How to get rid of the old topics forever?

Thanks
Sebastian
