--------------------------------------
Summary: ReassignPartitionsCommand does not check replication
factor
Key: KAFKA-4083
URL: https://issues.apache.org/jira/browse/KAFKA-4083
Project: Kafka
Issue Type: Bug
Components: admin, core
Affects Versions: 0.10.0.0, 0.9.0.0, 0.8.2.0
Environment: Linux 14.04 LTS
Reporter: Simon Wan Wenli
Assignee: Simon Wan Wenli
Priority: Minor
Fix For: 0.10.0.0, 0.9.0.0, 0.8.2.0
ReassignPartitionsCommand does not check whether the replication factor of a
partition is the same as existing replication factor, which may result that
different partitions of a topic have different number of partitions. More
specifically, TopicCommand will throw exception which contains "All partitions
should have the same number of replicas." as the message when the user tries to
add partitions. I think this loophole also may leave Kafka in a situation from
which it is difficult to recover.
