Summary: Should kafka-storage.sh accept a non-UUID for its
--cluster-id parameter?
Key: KAFKA-12505
URL: https://issues.apache.org/jira/browse/KAFKA-12505
Project: Kafka
Issue Type: New Feature
Reporter: Ron Dagostino
Should StorageTool support accepting non-UUIDs via its --cluster-id argument?
One purpose of the tool is to minimize the chance that a broker could use data
from the wrong volume (i.e. data from another cluster). Generating a random
UUID via the --random-uuid parameter encourages using a globally unique value
for every cluster and is consistent with the behavior today with ZooKeeper,
whereas allowing a non-UUID here would increase the chance that someone could
reuse a Cluster ID value across clusters and short-circuit the risk mitigation
that this tool provides.
