We should also make some adjustments to DescribeQuorumRequestTest since we have observers now.

Thanks for the changes @hachikuji . Do we need this for 3.3.0?

We did this to address this issue: https://issues.apache.org/jira/browse/KAFKA-13168. Do you think this is not needed anymore because we have this check in KafkaConfig?
// nodeId must not appear in controller.quorum.voters
require(!voterAddressSpecsByNodeId.containsKey(nodeId),
s"If ${KafkaConfig.ProcessRolesProp} contains just the 'broker' role, the node id $nodeId must not be included in the set of voters ${KafkaConfig.QuorumVotersProp}=${voterAddressSpecsByNode Id.asScala.keySet.toSet}")

Yes, that is what I was thinking. Because we require the voter set to be consistently defined on all nodes, it seems like it is good enough to ensure that any node which starts with just the "broker" role is not among the voters. Do you agree with that?

Okay. It is best we can do at the moment. We can revisit this when we have replicaUuid and storageId from KIP-853.

…orum (#12498) Currently we do not set the replicaId in fetches from brokers to the metadata quorum. It is useful to do so since that allows us to debug replication using the `DescribeQuorum` API.
