Subject Kafka 8.2.1 : ISR updation skipped
Date Fri, 18 Dec 2015 10:45:28 GMT
Hi All,

I'm Using a 2-node cluster (with 3rd zookeeper running on one of these
machines).

Due to some reason, the data is not being replicated to another kafka
process.

Kafka Version : kafka_2.10-0.8.2.1

# ./bin/kafka-topics.sh --zookeeper localhost:2181 --describe --topic topic1
Topic:topic1    PartitionCount:16       ReplicationFactor:2     Configs:
        Topic: topic1   Partition: 0    Leader: 1       Replicas: 0,1
Isr: 1
        Topic: topic1   Partition: 1    Leader: 1       Replicas: 1,0
Isr: 1


server.log:

[2015-12-18 03:42:10,071] INFO Partition [topic1,1] on broker 1: Expanding
ISR for partition [topic1,1] from 1 to 1,0 (kafka.cluster.Partition)
[2015-12-18 03:42:10,082] INFO Partition [topic1,1] on broker 1: Cached

[2015-12-18 03:42:10,084] INFO Partition [topic1,0] on broker 1: Expanding

Looks like some version mismatch wrt zookeepers.

Can someone please help on this.


Thank you.
