> If a producer publishes data to topic "foo/foo", the Kafka server ends up
> creating an invalid directory structure on the server. This corrupts the
> zookeeper data structure for the topic - /brokers/topics/foo/foo. This leads
> to rebalancing failures on the consumer as well as errors on the zookeeper
> based producer.
> We need to harden the invalid topic handling on the Kafka server side to
> avoid this.
