--------------------------------
Summary: Command-line tools should print what they do as part of
their usage command
Key: KAFKA-1292
URL: https://issues.apache.org/jira/browse/KAFKA-1292
Project: Kafka
Issue Type: Improvement
Reporter: Jay Kreps
It would be nice if you could get an explanation for each tool by running the
command with no arguments. Something like
bin/kafka-preferred-replica-election.sh is a little scary so it would be nice
to have it self-describe:
> bin/kafka-preferred-replica-election.sh
This command attempts to return leadership to the preferred replicas (if they
are alive) from whomever is currently the leader).
