Description

Running kafka-topics.sh -alter with an invalid -topic argument produces no output and exits with 0, indicating success.

$ bin/kafka-topics.sh --topic does-not-exist --alter --config invalid=xxx --zookeeper zkhost:2181
$ echo $?
0

An invalid topic name or a regular expression that matches 0 topics should at least print a warning.
