-----------------------------------
Summary: Metadata cache on the broker may have replica list may
have different order from zookeeper
Key: KAFKA-5329
URL: https://issues.apache.org/jira/browse/KAFKA-5329
Project: Kafka
Issue Type: Bug
Affects Versions: 0.10.2.1
Reporter: Jiangjie Qin
Fix For: 0.11.0.1
It looks that in {{PartitionStateInfo}} we are storing the replicas in a set
instead of a Seq. This causes the replica order to be lost. In most case it is
fine, but in the context of preferred leader election, the replica order
determines which replica is the preferred leader of a partition. It would be
useful to make the order always be consistent with the order in zookeeper.
