--------------------------------------
Summary: 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?)
