New Protocol Errors
It is proposed to use existing / add these error codes to the protocol.
Error | Description | Requests |
|---|---|---|
TopicAlreadyExistsTopicExists | Topic with this name already exists. | CreateTopic |
InvalidTopic (existing) | Topic name contains invalid characters or doesn't exist. | CreateTopic, AlterTopic, DeleteTopic |
InvalidPartitions | Partitions field is invalid (e.g. negative or increasing number of partitions in existing topic) | CreateTopic, AlterTopic |
InvalidReplicationFactor | ReplicationFactor field is invalid (e.g. negative) | CreateTopic, |
InvalidReplicaAssignment | ReplicaAssignment field is invalid (e.g. contains duplicates) |
|
InvalidTopicConfigurationInvalidConfiguration | Either topic-level config setting or value is incorrect. | Create |
DecreasePartitionsNotAllowed | Invalid Partitions argument: decreasing partitions is prohibited when altering topic. | Alter |
ReassignPartitionsInProgress | Reassign partitions procedure has been already started. | AlterCreateTopic |
Generally, a client should have enough context to provide descriptive error message.
The same notation as in A Guide To The Kafka Protocol is used here.
