Kafka leader vs Kafka partition leader election

  1. Kafka cluster can have leader broker? Who elects this?
  2. As far as i know, Kafka brokers rebalance partition leader when some brokers have failure. So initial partition when topic is created, leaders are elected by zookeeper or brokers?
  3. When i set 1 zookeeper + 3 kafka brokers and then force exit broker 1. But partition's leader is just set NONE and didn't rebalance. So i solved this problem by setting auto.rebalance config or adding two more zookeeper nodes(total 3). But if partition leaders are elected by brokers how 3 zookeepers solved this? Even i didn't config auto rebalance.

All brokers are equal for replication purposes.

One broker is elected as a Controller to manage cluster operations and partition leadership for client interaction.

If broker 1 was the controller or is running Zookeeper as well, and you shutdown the whole server, then you'd should expect leader election to fail until a new controller is selected.
