> We are running Kafka (vesion kafka_2.11-0.10.1.0) in a 2 node cluster. We
> have 2 producers (Java API) acting on different topics. Each topic has single
> partition. The topic where we had this issue, has one consumer running. This
> set up has been running fine for 3 months, and we saw this issue. All the
> suggested cases/solutions for this issue in other forums don't seem to apply
> for my scenario.
> Exception at producer;
> {code}
> -2017-11-25T17:40:33,035 [kafka-producer-network-thread | producer-1] ERROR
> client.producer.BingLogProducerCallback - Encountered exception in sending
> message ; > org.apache.kafka.common.errors.NotLeaderForPartitionException:
> This server is not the leader for that topic-partition.
> {code}
> We haven't enabled retries for the messages, because this is transactional
> data and we want to maintain the order.
> Producer config:
> {code}
> bootstrap.servers : server1ip:9092
> acks :all
> retries : 0

> value.serializer : org.apache.kafka.common.serialization.StringSerializer
> {code}
> We are connecting to server1 at both producer and consumer. The controller
> log at server2 indicates there is some shutdown happened at during sametime,
> but I dont understand why this happened.
