Summary: DescribeLogDirsResponseData#results#topics have
unexpected topics having empty partitions
Key: KAFKA-16807
URL: https://issues.apache.org/jira/browse/KAFKA-16807
Project: Kafka
Issue Type: Bug
Reporter: Chia-Ping Tsai
Assignee: Chia-Ping Tsai
ReplicaManager [0] could generate a response having unexpected topics which
have empty partitions. The root cause is it always generate the topic
collection even though they have no matched partitions.
That is not a issue to Kafka clients, since we loop the "partitions" to fill
all future responses [1]. Hence, those unexpected topics won't be existent in
the final results.
However, that could be a issue to the users who implement Kafka client based on
Kafka protocol [2]
