--------------------------------
Fix Version/s: (was: 0.8.3)
> controller state gets stuck in message after execute
> ----------------------------------------------------
>
> Key: KAFKA-1665
> URL: https://issues.apache.org/jira/browse/KAFKA-1665
> Project: Kafka
> Issue Type: Bug
> Reporter: Joe Stein
>
> I had a 0.8.1.1 Kafka Broker go down, and I was trying to use the reassign
> partition script to move topics off that broker. When I describe the topics,
> I see the following:
> Topic: mini__022____active_120__33__mini Partition: 0 Leader: 2131118
> Replicas: 2131118,2166601,2163421 Isr: 2131118,2166601
> This shows that the broker “2163421” is down. So I create the following file
> /tmp/move_topic.json:
> {
> "version": 1,
> "partitions": [
> {
> "topic": "mini__022____active_120__33__mini",
> "partition": 0,
> "replicas": [
> 2131118, 2166601, 2156998
> ]
> }
> ]
> }
> And then do this:
> ./kafka-reassign-partitions.sh --execute --reassignment-json-file
> /tmp/move_topic.json
> Successfully started reassignment of partitions
> {"version":1,"partitions":[{"topic":"mini__022____active_120__33__mini","partition":0,"replicas":[2131118,2166601,2156998]}]}
> However, when I try to verify this, I get the following error:
> ./kafka-reassign-partitions.sh --verify --reassignment-json-file
> /tmp/move_topic.json
> Status of partition reassignment:
> ERROR: Assigned replicas (2131118,2166601,2156998,2163421) don't match the
> list of replicas for reassignment (2131118,2166601,2156998) for partition
> [mini__022____active_120__33__mini,0]
> Reassignment of partition [mini__022____active_120__33__mini,0] failed
> If I describe the topics, I now see there are 4 replicas. This has been like
> this for many hours now, so it seems to have permanently moved to 4 replicas
> for some reason.
> Topic:mini__022____active_120__33__mini PartitionCount:1 ReplicationFactor:4
> Configs:
> Topic: mini__022____active_120__33__mini Partition: 0 Leader: 2131118
> Replicas: 2131118,2166601,2156998,2163421 Isr: 2131118,2166601
> If I re-execute and re-verify, I get the same error. So it seems to be wedged.
