Jun Rao created KAFKA-762:
-----------------------------
Summary: Improve second replica assignment
Key: KAFKA-762
URL: https://issues.apache.org/jira/browse/KAFKA-762
Project: Kafka
Issue Type: Improvement
Components: core
Affects Versions: 0.8
Reporter: Jun Rao
Assignee: Jun Rao
Priority: Blocker
Currently, for partitions from different topics, if the first replica is
assigned to the same broker, their second replica is also assigned to the same
broker. This means that when a broker fails, many leaders on the failed broker
will be moved to the same broker, and thus introduces more load on that broker.
