I'm trying to perform an upgrade of 2 kafka cluster of 5 instances, When
I'm doing the switch between 0.10.0.1 and 0.10.1.0 or 0.10.2.0, I saw
that ISR is lost when I upgrade one instance. I didn't find out yet
anything relevant about this problem, logs seems just fine.
eg.
kafka-topics.sh --describe --zookeeper kazoo002.#####.prv --topic redirects
Topic:redirects PartitionCount:6 ReplicationFactor:2
Configs:retention.bytes=10737418240
Topic: redirects Partition: 0 Leader: 1 Replicas: 1,2
Isr: 1,2
Topic: redirects Partition: 1 Leader: 2 Replicas: 2,0
Isr: 2
Topic: redirects Partition: 2 Leader: 1 Replicas: 0,1
Isr: 1
Topic: redirects Partition: 3 Leader: 1 Replicas: 1,0
Isr: 1
Topic: redirects Partition: 4 Leader: 2 Replicas: 2,1
Isr: 2,1
Topic: redirects Partition: 5 Leader: 2 Replicas: 0,2
Isr: 2
It run with Zookeeper 3.4.6.
As those clusters are in production, I didn't try to migrate more than 1
instance after spotting this ISR problem, and then rollback to the
original version 0.10.0.1.
Any update about this would be greatly receive.
