---------------------------------
Summary: "replica-assignment" option in "bin/kakfa-topics.sh"
doesn't work with "alter"
Key: KAFKA-1656
URL: https://issues.apache.org/jira/browse/KAFKA-1656
Project: Kafka
Issue Type: Improvement
Components: tools
Affects Versions: 0.8.1.1
Environment: all
Reporter: jayden sun
Priority: Minor
"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.
