> KafkaConsumer should validate topics/TopicPartitions on subscribe/assign
> ------------------------------------------------------------------------
>
> Key: KAFKA-5848
> URL: https://issues.apache.org/jira/browse/KAFKA-5848
> Project: Kafka
> Issue Type: Bug
> Components: clients
> Affects Versions: 0.11.0.0
> Reporter: Matthias J. Sax
> Priority: Minor
>
> Currently, {{KafkaConsumer}} checks if the provided topics on {{subscribe()}}
> and {{TopicPartition}} on {{assign()}} don't contain topic names that are
> {{null}} or an empty string.
> However, it could do some more validation:
> - check if invalid topic characters are in the string (this might be
> feasible for {Patterns}}, too?)
> - check if provided partition numbers are valid (ie, not negative and maybe
> not larger than the available partitions?)
