New Protocol Errors
It is proposed to add these error codes to the protocol.
Error | Description | Requests |
|---|---|---|
TopicAlreadyExists | Topic with this name already exists. | CreateTopicRequest |
InvalidArgumentTopicName | Topic name contains invalid characters | CreateTopicRequest |
InvalidArgumentPartitions | Either partition field is invalid (e.g. negative), or not defined when needed. | CreateTopicRequest, AlterTopicRequest |
InvalidArgumentReplicationFactor | Either replication-factor field is invalid (e.g. negative), or not defined when needed. | CreateTopicRequest, |
InvalidArgumentReplicaAssignment | Either replication-factor field is invalid (e.g. contains duplicates), or not defined when needed. |
|
InvalidArgumentTopicConfig | Either topic-level config setting or value is incorrect. | CreateTopicRequest, AlterTopicRequest |
DecreasePartitionsNotAllowed | Invalid partitions argument: decreasing partitions is prohibited when altering topic. | AlterTopicRequest |
PreferredReplicaLeaderElectionInProgress | Preferred replica leader election procedure has been already started. | PreferredReplicaLeaderElectionRequest |
ReassignPartitionsInProgress | Reassign partitions procedure has been already started. | AlterTopicRequest |
| MultipleInstructionsForOneTopic | Only one mutation is allowed at once: e.g. change topic replication factor or change topic config | CreateTopic, AlterTopicRequest |
MultipleTopicInstructionsInOnebatch | Multiple topic instructions for the same topic in one batch request | CreateTopicRequest, AlterTopicRequest, DeleteTopicRequest |
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.
