> Key: KAFKA-1656

> Project: Kafka
> Issue Type: Improvement

> Labels: newbie

> "replica-assignment" option in "bin/kakfa-topics.sh" works only with
> "--create" and doesn't work with "--alter", but the config comment is
> somewhat confusing.
> For example:
> bin/kafka-topics.sh --create --zookeeper 10.0.44.137:2181
> --replica-assignment 1:2,1:2 --partitions 2 --topic topic
> i use the command above to create a topic with two partitions on broker 1 and
> 2.
> and then i want to change partition count from two to four, and the newly
> created partition on broker 3 and 4.
> So i try the command:
> bin/kafka-topics.sh --alter --zookeeper 10.0.44.137:2181 --replica-assignment
> 3:4,3:4 --partitions 4 --topic topic
> But it does not works!!! "replica-assignment" can't be used with "partitions".
> What i can do is to add partitions like this:
> bin/kafka-topics.sh --alter --zookeeper 10.0.44.137:2181 --partitions 4
> --topic topic
> and then use the partition reassignment command to change the brokers for
> newly partitions to 3 and 4.
> So,i think "or altered" in the comment for "--replica-assignment" should be
> removed.
