Description

I'm using Kafka 0.10.0.1 with an SASL authentication on the client:

kafka_client_jaas.conf

KafkaClient {
    org.apache.kafka.common.security.plain.PlainLoginModule required
    username="guillaume"
    password="secret";
};

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).
