Veniamin Kalegin created KAFKA-12396:
----------------------------------------
Summary: Dedicated exception for kstreams when null key received
Key: KAFKA-12396
URL: https://issues.apache.org/jira/browse/KAFKA-12396
Project: Kafka
Issue Type: Improvement
Components: streams
Affects Versions: 2.6.0
Reporter: Veniamin Kalegin
If kstreams application received null as a key (thanks to QA), kstream app
gives long and confusing stack trace, it would be nice to have shorter and
specific exception instead of
{{org.apache.kafka.streams.errors.StreamsException: Exception caught in
process. taskId=0_0, processor=KSTREAM-SOURCE-0000000000, topic=(hidden),
partition=0, offset=3722, stacktrace=java.lang.NullPointerException}}
