It is proposed to use existing / add these error codes to the protocol.

InvalidTopic (existing)InvalidArgumentTopicName | Topic name contains invalid characters. | CreateTopicRequest | Create, Alter, Delete |
InvalidPartitionsInvalidArgumentPartitions | Either partition field is invalid (e.g. negative) | CreateTopicRequestCreate, AlterTopicRequest Alter | |
InvalidArgumentReplicationFactorInvalidReplicationFactor | Either replication-factor field is invalid (e.g. negative) | CreateTopicRequestCreate, | |
InvalidArgumentReplicaAssignmentInvalidReplicaAssignment | Either replication assignment field is invalid (e.g. contains duplicates) |

| MultipleInstructionsForOneTopic | Only one mutation is allowed at once: e.g. change topic replication factor or change topic config. | CreateTopic, AlterTopicRequest | |

Generally, the Admin Client (see section 3) or another request dispatcher should have enough context to provide descriptive error message.
The same notation as in A Guide To The Kafka Protocol is used here.
