Viliam Durina created KAFKA-5874:
------------------------------------
Summary: Incorrect command line handling
Key: KAFKA-5874
URL: https://issues.apache.org/jira/browse/KAFKA-5874
Project: Kafka
Issue Type: Bug
Components: admin
Affects Versions: 0.11.0.0, 0.10.2.0
Environment: Probably unrelated, but Windows 10 in this case
Reporter: Viliam Durina
Priority: Minor
Extra parameters on command line are silently ignored. This leads to confusion.
For example, I did this command:
`kafka-topics.bat --alter --topic my_topic partitions 3 --zookeeper localhost`
Seemingly innocuous command took about 3 seconds and output nothing. It took me
a while to realize I missed "--" before "partitions", after which I got a
confirmation on output.
Erroneous command lines should produce error output.
