-----------------------------------
Summary: The list of brokers for fetching metadata should be
shuffled
Key: KAFKA-890
URL: https://issues.apache.org/jira/browse/KAFKA-890
Project: Kafka
Issue Type: Bug
Components: core
Affects Versions: 0.8
Reporter: Neha Narkhede
Assignee: Neha Narkhede
Priority: Blocker
The list of brokers in the metadata request is never shuffled. Which means that
if some clients are not using a VIP for metadata requests, the first broker
ends up servicing most metadata requests, leaving imbalanced load on the
brokers. This issue is even more pronounced when there are several thousand
clients talking to a cluster each using a broker list to fetch metadata.
