-------------------------------------
Summary: kafka-storage.sh should disallow invalid cluster ids
Key: KAFKA-20617
URL: https://issues.apache.org/jira/browse/KAFKA-20617
Project: Kafka
Issue Type: Improvement
Reporter: Gaurav Narula
Assignee: Gaurav Narula
{{kafka-storage.sh format}} accepts a {{cluster-id}} argument. While the
recommendation is that users can generate a random uuid using
{{kafka-storage.sh random-uuid}} command, the users are free to generate a
cluster id out of band.
The {{format}} command should therefore perform validation on the cluster-id
passed as we risk using one which is invalid. Gotchas can include:
* Not using URLEncoding when using base64
* Using base64 encoding with padding
* Being unlucky and using a reserved UUID
