> The exit code is sometimes set properly when other code paths cause the
> command to exit, or in versions < 3.7:
> {noformat}
> % bin/kafka-leader-election.sh
> This tool attempts to elect a new leader for a set of topic partitions. The
> type of elections supported are preferred replicas and unclean replicas.

> This appears to be a regression in 3.7.0, and since a shell script may be
> relying on the return code from this command, this is something we should fix
> in the next release.
