Hello * I am running Kafka(*0.10.2.0*) on windows from the past one year ...
But off late there has been unique Broker issues that I have observed 4-5 times in last 4 months. Kafka setup cofig... *3 ZK Instances running on 3 different Windows Servers, 7 Kafka Broker nodes running on single windows machine with different disk for logs directory.... * *My Kafka has 2 Topics with partition size 50 each , and replication factor of 3.* *My partition logic selection*: Each message has a unique ID and logic of selecting partition is ( unique ID % 50), and then calling Kafka producer API to route a specific message to a particular topic partition . But of-late there has been a unique case that's cropping out in Kafka broker nodes, [2017-12-02 02:47:40,024] ERROR [ReplicaFetcherThread-0-4], Error for partition [__consumer_offsets,15] to broker 4:org.apache.kafka.common.errors.NotLeaderForPartitionException: This server is not the leader for that topic-partition. (kafka.server.ReplicaFetcherThread) The entire server.log is filled with these logs, and its very huge too , please help me in understanding under what circumstances these can occur, and what measures I need to take..
