>             Project: Kafka
>          Issue Type: Bug
>          Components: clients
>    Affects Versions: 2.6.0
>         Environment: Prod
>            Reporter: Avi Youkhananov

> 1.
> org.apache.kafka.clients.producer.Callback interface has method onCompletion(...)
> Which says as part of the documentation :
> *The metadata for the record that was sent (i.e. the partition and offset). *An empty metadata with -1 value for all fields* except for topicPartition will be returned if an error occurred.
> We got an NPE from doSend(...) method in org.apache.kafka.clients.producer.KafkaProducer 
> Which can occur in case ApiException was thrown ...
> In case of ApiException it uses the regular callback instead of InterceptorCallback which also may cover the NPE.
> 2. More over RecordMetadata has method partition() which return int but can also throw NPE because TopicPartition might be null.
> Stack trace attached.
