-----------------------------------
Summary: partition replica assignment map in the controller should
be a Set
Key: KAFKA-830
URL: https://issues.apache.org/jira/browse/KAFKA-830
Project: Kafka
Issue Type: Bug
Reporter: Neha Narkhede
Assignee: Neha Narkhede
Priority: Blocker
Fix For: 0.8
partitionReplicaAssignment currently stores the list of assigned replicas as a
sequence. When a broker comes online, the replica state machine adds the broker
to the list of assigned replicas. It should do that only if the replica is
already not in the list of assigned replicas. This causes the replication
factor to be incorrectly calculated
