sciclon2 opened a new pull request, #14094: URL: https://github.com/apache/kafka/pull/14094
This PR aims to fix a bug, basically there is a mismatch between the Kafka users and the list tool output. Kafka allows to create users with special characters that are encoded before storing them to ZK. Later they are decoded when they are requested by Kafka. In our company we rely in the list users feature to check if the Kafka users exists, the problem is the users listed by kafa-configs.sh were not decoding the users and showing them with the string encoded. For example if I want to create `myu...@myuser.com` COMMAND ```bash /etc/new_kafka/bin/kafka-configs.sh --bootstrap-server localhost:9092 --alter --add-config 'SCRAM-SHA-256=[iterations=4096,password=blabla],SCRAM-SHA-256=[password=blabla]' --entity-type users --entity-name myu...@myuser.com ``` OUTPUT ```bash Completed updating config for user myu...@myuser.com ``` As we can see the user is properly created but when we list it we see this: ```bash kafka-configs.sh --bootstrap-server localhost:9092 --describe --entity-type users|grep myuser ``` OUTPUT ```bash SCRAM credential configs for user-principal 'myuser%40myuser.com' are SCRAM-SHA-256=iterations=8192, SCRAM-SHA-512=iterations=4096 ``` So the problem is the describe is not decoding the users, in our case this is a problem as after creating the user we use this command to make sure the user exists fro future operations, for example password change. more information in the [ticket](https://issues.apache.org/jira/browse/KAFKA-15243) TEST: After adding the patch users are properly listed: ```bash kafka-configs.sh --bootstrap-server localhost:9092 --alter --add-config 'SCRAM-SHA-256=[iterations=4096,password=blabla],SCRAM-SHA-256=[password=blabla]' --entity-type users --entity-name myu...@myuser.com Completed updating config for user myu...@myuser.com. ``` NOW THE USER IS LISTED WITH THE REAL NAME ```bash kafka-configs.sh --bootstrap-server localhost:9092 --describe --entity-type users|grep myu...@myuser.com SCRAM credential configs for user-principal 'myu...@myuser.com' are SCRAM-SHA-256=iterations=4096 ``` -- This is an automated message from the Apache Git Service.
