Hi, I have a kafka cluster consisting of two servers. I created a topic "ReplicatedTopic" with 3 partitions and replication factor of 2.
Next, I shutdown one the servers for 20 sec and return it back again. Then, I looked at status of topic "ReplicatedTopic" and I got the followings: Topic:ReplicatedTopic PartitionCount:3 ReplicationFactor:2 Configs: Topic: ReplicatedTopic Partition: 0 Leader: 1 Replicas: 0,1 Isr: 1 Topic: ReplicatedTopic Partition: 1 Leader: 1 Replicas: 1,0 Isr: 1 Topic: ReplicatedTopic Partition: 2 Leader: 1 Replicas: 0,1 Isr: 1 Although broker zero is back. it seems it is not in sync with leader and in fact it never became in sync again. Now question is how to make first broker in sync again so it appears both in "isr" list and also it becomes leader for one of the partitions? best, /Shahab
