-----------------------------------
Summary: Duplicate broker ids allowed in replica assignment
Key: KAFKA-1653
URL: https://issues.apache.org/jira/browse/KAFKA-1653
Project: Kafka
Issue Type: Bug
Components: tools
Affects Versions: 0.8.1.1
Reporter: Ryan Berdeen
The reassign partitions command and the controller do not ensure that all
replicas for a partition are on different brokers. For example, you could set
1,2,2 as the list of brokers for the replicas.
kafka-topics.sh --describe --under-replicated will list these partitions as
under-replicated, but I can't see a reason why the controller should allow this
state.
