----------------------------------
> New consumer should not require the deprecated partition.assignment.strategy
> ----------------------------------------------------------------------------
>
> Key: KAFKA-16786
> URL: https://issues.apache.org/jira/browse/KAFKA-16786
> Project: Kafka
> Issue Type: Bug
> Components: clients, consumer
> Affects Versions: 3.7.0
> Reporter: Lianet Magrans
> Assignee: Lianet Magrans
> Priority: Major
> Labels: kip-848-client-support
> Fix For: 3.8.0
>
>
> The partition.assignment.strategy config is deprecated with the new consumer
> group protocol KIP-848. With the new protocol, server side assignors are
> supported for now, defined in the property
> group.remote.assignor, and with default values selected by the broker, so
> it's not even a required property.
> The new AsyncKafkaConsumer supports the new protocol only, but it currently
> throws an IllegalStateException if a call to subscribe is made and the
> deprecated config partition.assignment.strategy is empty (see
> [throwIfNoAssignorsConfigured|https://github.com/apache/kafka/blob/056d232f4e28bf8e67e00f8ed2c103fdb0f3b78e/clients/src/main/java/org/apache/kafka/clients/consumer/internals/AsyncKafkaConsumer.java#L1715]).
>
> We should remove the reference to ConsumerPartitionAssignor in the
> AsyncKafkaConsumer, along with it's validation for non-empty on subscribe
> (only use it has)
