Mickael Hemri commented on KAFKA-1019:
--------------------------------------
I tried with zookeeper 3.3.6 and we have the same issue.
To reproduce:
Create a topic named testid
{code}bin/kafka-topics.sh --topic testid --replication-factor 3 --partition 3
--zookeeper 127.0.0.1:2181/kafka --create
Created topic "testid".{code}
{code}./bin/kafka-topics.sh --topic testid --zookeeper 127.0.0.1:2181/kafka
--describe
Topic:testid PartitionCount:3 ReplicationFactor:3 Configs:
Topic: testid Partition: 0 Leader: 31985 Replicas:
31985,9920,4580 Isr: 31985,9920,4580
Topic: testid Partition: 1 Leader: 4580 Replicas:
4580,31985,9920 Isr: 4580,31985,9920
Topic: testid Partition: 2 Leader: 9920 Replicas:
9920,4580,31985 Isr: 9920,4580,31985
{code}
Ok great, we have leaders and /brokers/topics/testid/partitions in zookeeper
Delete testid topic
{code}bin/kafka-run-class.sh kafka.admin.DeleteTopicCommand --topic testid
--zookeeper 127.0.0.1:2181/kafka
deletion succeeded!
{code}
Create again a topic named testid
{code}bin/kafka-topics.sh --topic testid --replication-factor 3 --partition 3
--zookeeper 127.0.0.1:2181/kafka --create
Created topic "testid".{code}
Now check:
{code}./bin/kafka-topics.sh --topic testid --zookeeper 127.0.0.1:2181/kafka
--describe
Topic:testid PartitionCount:3 ReplicationFactor:3 Configs:
Topic: testid Partition: 0 Leader: none Replicas:
31985,4580,9920 Isr:
Topic: testid Partition: 1 Leader: none Replicas:
4580,9920,31985 Isr:
Topic: testid Partition: 2 Leader: none Replicas:
9920,31985,4580 Isr:{code}
As you can see we have no leader when we create the topic after a deletion. And
there is no /brokers/topics/testid/partitions in zookeeper
It works again with a different topic name, so it seems that something is not
properly deleted with DeleteTopicCommand command.
We reproduced it on 3 differents zookeeper chroot: 127.0.0.1:2181/kafka,
127.0.0.1:2181/kafka2 and 127.0.0.1:2181/kafka3
Thanks
