----------------------------------
Summary: Replicas collections should use List instead of Set in
order to maintain order
Key: KAFKA-3226
URL: https://issues.apache.org/jira/browse/KAFKA-3226
Project: Kafka
Issue Type: Bug
Affects Versions: 0.9.0.0
Reporter: Grant Henke
Assignee: Grant Henke
Fix For: 0.9.0.1
Found an issue where LeaderAndIsrRequest and UpdateMetadataRequest store the
replicas in a Set. This potentially changes the order of the replicas list,
which is important because the first replica is the "preferred" replica.
The question is, do these requests need to go through a
deprecation/compatibility cycle, or are they considered internal messages?
