Hello, I'm doing some tests about behaviors of Kafka under faulty circumstances.
Here are my configs(one of total 3, comments removed): broker.id=0 listeners=PLAINTEXT://:9092 advertised.listeners=PLAINTEXT://10.0.8.233:9092 num.network.threads=3 num.io.threads=8 socket.send.buffer.bytes=102400 socket.receive.buffer.bytes=102400 socket.request.max.bytes=104857600 log.dirs=/tmp/kafka-logs num.partitions=1 num.recovery.threads.per.data.dir=1 default.replication.factor=3 replication.factor=3 acks=all offsets.topic.replication.factor=3 transaction.state.log.replication.factor=3 transaction.state.log.min.isr=2 min.insync.replicas = 2 log.retention.hours=168 log.segment.bytes=1073741824 log.retention.check.interval.ms=300000 zookeeper.connect=localhost:2181 zookeeper.connection.timeout.ms=18000 group.initial.rebalance.delay.ms=3000 I created a topic with 1 partition and 3 replicas, and produce/consume with those shell tools shipped with Kafka. And I find even if I kill 2 processes of Kafka with `kill -9`, the topic is still writable. I believe this would cause potential data loss. I don't know if I misconfigured something, could someone review it for me? I'm testing with kafka_2.12-2.5.0 Best, Can Zhang
