> It appears that deleting a topic and creating it at the same time can cause NSEE, what
later results in a forced controller shutdown.
> Most probably topics are being created because consumers/producers are still active (yes,
this means the deletion is happening blindly).
> The main problem here (for me) is the controller switch, the data loss and following
unclean election is acceptable (as we admit to deleting blindly).
> Environment description:
> 20 kafka brokers
> 80k partitions (20k topics 4partitions each)
> 3 node ZK
