             Summary: KRaft Controller cannot create topic with more partitions 
than racks
                 Key: KAFKA-12897
                 URL: https://issues.apache.org/jira/browse/KAFKA-12897
             Project: Kafka
          Issue Type: Bug
          Components: controller
    Affects Versions: 3.0.0
            Reporter: Ron Dagostino
            Assignee: Ron Dagostino
             Fix For: 3.0.0


https://github.com/apache/kafka/pull/10494 introduced a bug in the KRaft 
controller where the controller will loop forever in `StripedReplicaPlacer` 
trying to identify the racks on which to place partitions if the number of 
requested partitions in a CREATE_TOPICS request exceeds the number of effective 
racks ("effective" meaning a single rack if none are specified).
