> Seems like the broker doesn't like topic names of 254 chars or more when creating using kafka-topics.sh --create.
> The problem does not seem to arise when topic is created through automatic topic creation.
> How to reproduce:
> {code}
> TOPIC=$(printf 'd%.0s' {1..254} ) ; bin/kafka-topics.sh --zookeeper 0 --create --topic $TOPIC --partitions 1 --replication-factor 1
> {code}
> {code}
