----------------------------------------
Summary: kafka-configs.sh does not work while changing the sasl
jaas configurations.
Key: KAFKA-12529
URL: https://issues.apache.org/jira/browse/KAFKA-12529
Project: Kafka
Issue Type: Bug
Reporter: kaushik srinivas
We are trying to use kafka-configs script to modify the sasl jaas
configurations, but unable to do so.
Command used:
./kafka-configs.sh --bootstrap-server localhost:9092 --entity-type brokers
--entity-name 59 --alter --add-config 'sasl.jaas.config=KafkaServer \{\n
org.apache.kafka.common.security.plain.PlainLoginModule required \n
username=\"test\" \n password=\"test\"; \n };'
error:
requirement failed: Invalid entity config: all configs to be added must be in
the format "key=val".
command 2:
kafka-configs.sh --bootstrap-server localhost:9092 --entity-type brokers
--entity-name 59 --alter --add-config
'sasl.jaas.config=[username=test,password=test]'
output:
command does not return , but kafka broker logs below error:

METADATA during SASL handshake.)"}}
We have below issues:
1. If one installs kafka broker with SASL mechanism and wants to change the
SASL jaas config via kafka-configs scripts, how is it supposed to be done ?
does kafka-configs needs client credentials to do the same ?
2. Can anyone point us to example commands of kafka-configs to alter the
sasl.jaas.config property of kafka broker. We do not see any documentation or
examples for the same.
