Rajini Sivaram created KAFKA-5735: ------------------------------------- Summary: Client-ids are not handled consistently by clients and broker Key: KAFKA-5735 URL: https://issues.apache.org/jira/browse/KAFKA-5735 Project: Kafka Issue Type: Bug Components: clients, core Affects Versions: 0.11.0.0 Reporter: Rajini Sivaram Assignee: Rajini Sivaram Fix For: 1.0.0
At the moment, Java clients expect client-ids to use a limited set of characters so that they can be used without quoting in metrics. kafka-configs.sh allows quotas to be defined only for that limited set. But the broker does not validate client-ids. And the documentation does not mention any limitations. We need to either limit characters used in client-ids, document and validate them or we should allow any characters and treat them consistently in the same way as we handle user principals. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
