-----------------------------------
Summary: Duplicate error handling in kafka-server-start.sh and
actual Kafka class
Key: KAFKA-8247
URL: https://issues.apache.org/jira/browse/KAFKA-8247
Project: Kafka
Issue Type: Bug
Components: core
Affects Versions: 2.1.1
Reporter: Sönke Liebau
There is some duplication of error handling for command line parameters that
are passed into kafka-server-start.sh
The shell script prints an error, if no arguments are passed in, effectively
causing the same check in
[Kafka|https://github.com/apache/kafka/blob/92db08cba582668d77160b0c2853efd45a1b809b/core/src/main/scala/kafka/Kafka.scala#L43]
to never be triggered, unless the only option that is specified is -daemon,
which would be removed before passing arguments to the java class.
While not in any way critical I don't think that this is intended behavior. I
think we should remove the extra check in kafka-server-start.sh and leave
argument handling up to the Kafka class.
