Hello,
in our Kafka clusters we sometimes observe a specific ERROR log-statement, and
therefore we have doubts whether it is already running sable in our
configuration. This occurs every now and then, like two or three times in a
day. It is actually the predominant ERROR log-statement in our cluster. Example:
[2016-12-06 17:14:50,909] ERROR [ReplicaFetcherThread-0-3], Error for partition
[<topic_name>,<partition_number>] to broker
3:org.apache.kafka.common.errors.NotLeaderForPartitionException: This server is
not the leader for that topic-partition. (kafka.server.ReplicaFetcherThread)
We already asked Google, but we did not find sufficient answers to our
questions, therefore I am asking on the mailing list:
1. What are the possible reasons for this particular error?
2. What are the implications of it?
3. What can be done to prevent it?
Best Regards,
Sven
