Swapnil Ghike created KAFKA-1087: ------------------------------------ Summary: Empty topic list causes consumer to fetch metadata of all topics Key: KAFKA-1087 URL: https://issues.apache.org/jira/browse/KAFKA-1087 Project: Kafka Issue Type: Bug Reporter: Swapnil Ghike Assignee: Swapnil Ghike
The ClientUtils fetches metadata for all topics if the topic set is empty. If the topic list of a consumer is empty, the following happens if a rebalance is triggered: - LeaderFinderThread waits on a condition - The fetcher is restarted and it signals the aforementioned condition - LeaderFinderThread obtains metadata for all topics since the topic list is empty. -- This message was sent by Atlassian JIRA (v6.1#6144)
