> 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).
