> Remove usage of AdminClient from KafkaSource logic
> --------------------------------------------------
>
> Key: FLINK-27137
> URL: https://issues.apache.org/jira/browse/FLINK-27137
> Project: Flink
> Issue Type: Improvement
> Components: Connectors / Kafka
> Affects Versions: 1.15.0, 1.14.4
> Reporter: Gyula Fora
> Priority: Critical
>
> Parts of the KafkaSource logic (specifically the KafkaSourceEnumerator) uses
> the Kafka AdminClient instead of the KafkaConsumer.
> It seems that the KafkaConsumer already provides all the necessary
> information that the enumerator needs so there is no reason for introducing
> the AdminClient.
> In some environments using the AdminClient can be problematic even if we are
> not using certaing features.
