SASL Authentication Errors Don't Invoke Error Callback

[yungFundamental]

Hey there,

This issue is referenced in the following confluent Kafka python client issue. It was assigned a year and a half ago, but not fixed.

Basically, the problem is that authentication errors, including invalid credential responses, are retried no matter what. This means that the error cannot be distinguished from timeouts. I aim to change this so that the error cb will be invoked with the AUTHENTICATION error.

I want to be the one to implement this, and I am currently working on changing this behavior on my local branch. I am new to open-source development, and if there is anything I should know during the development phase, please let me know. Feel free to [contact me](mailto: [email protected]) for anything regarding this issue and its development.
