Edoardo Comar commented on KAFKA-4180:
--------------------------------------
I have updated the PR based on the discussion in the mailing list - namely the
key used to cache `LoginManager` instances.
I have retired KIP-83, the PR that closes this issue is mostly based on KIP-85
and associated https://issues.apache.org/jira/browse/KAFKA-4259
> Shared authentication with multiple active Kafka producers/consumers
> --------------------------------------------------------------------
>
> Key: KAFKA-4180
> URL: https://issues.apache.org/jira/browse/KAFKA-4180
> Project: Kafka
> Issue Type: Bug
> Components: producer , security
> Affects Versions: 0.10.0.1
> Reporter: Guillaume Grossetie
> Assignee: Mickael Maison
> Labels: authentication, jaas, loginmodule, plain, producer,
> sasl, user
>
> I'm using Kafka 0.10.0.1 with an SASL authentication on the client:
> {code:title=kafka_client_jaas.conf|borderStyle=solid}
> KafkaClient {
> org.apache.kafka.common.security.plain.PlainLoginModule required
> username="guillaume"
> password="secret";
> };
> {code}
> When using multiple Kafka producers the authentification is shared [1]. In
> other words it's not currently possible to have multiple Kafka producers in a
> JVM process.
> Am I missing something ? How can I have multiple active Kafka producers with
> different credentials ?
> My use case is that I have an application that send messages to multiples
> clusters (one cluster for logs, one cluster for metrics, one cluster for
> business data).
