Yes, the leader should move to K2 or K3. You can check the controller log
on all 3 machines to find out where the new leader is placed. It is not
guaranteed to move back to K1 when you restart it 2 hours later, however.

> I have a three brokers (K1, K2, K3) cluster using Kafka 0.8.2 and a

> I have a producer publishing messages in the topic every minuts (1+
> I have a consumergroup consuming messages every hour.
> The offset of this consumergroup for this topic is stored in zookeeper.
