Exception while loading Zookeeper JAAS

[rajeshbala01]

While following the step mentioned in production-secure-deploy to enable authentication to zookeeper via digest i am getting below error.

creds-zookeeper-sasl-digest-users.json

{ "kafka": "kafka-secret" }

creds-kafka-zookeeper-credentials.txt

username="kafka" password="kafka-secret"

[ERROR] 2021-08-30 07:48:56,286 [main] kafka.server.KafkaServer error - Fatal error during KafkaServer startup.

Did you create the secrets as mentioned in the link: https://github.com/confluentinc/confluent-kubernetes-examples/tree/master/security/production-secure-deploy#provide-authentication-credentials Please also check if there is any line break in the creds-kafka-zookeeper-credentials.txt and creds-zookeeper-sasl-digest-users.json files.

@MosheBlumbergX @ptyagii @rajeshbala01 I happened across this same problem today. It seems to be because the example files shown above are using the CRLF line ending. Switching them to LF line ending fixed it for me.

    If file reports "CRLF line terminators", the file is DOS-style
    If file reports "CR line terminators", the file is Mac-style
    If file doesn't mention line terminators, the file is Unix-style

I think it depends on the editor you use.
