Reporter: Abhi
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 . My Each Broker Properties look like this {{broker.id=0 port:9093 num.network.threads=3 num.io.threads=8 socket.send.buffer.bytes=102400 socket.receive.buffer.bytes=102400 socket.request.max.bytes=104857600 offsets.retention.minutes=360 advertised.host.name=1.1.1.2 advertised.port:9093 ctories under which to store log files log.dirs=C:\\kafka_2.10-0.10.2.0-SNAPSHOT\\data\\kafka-logs num.partitions=1 num.recovery.threads.per.data.dir=1 log.retention.minutes=360 log.segment.bytes=52428800 log.retention.check.interval.ms=300000 log.cleaner.enable=true log.cleanup.policy=delete log.cleaner.min.cleanable.ratio=0.5 log.cleaner.backoff.ms=15000 log.segment.delete.delay.ms=6000 auto.create.topics.enable=false zookeeper.connect=1.1.1.2:2181,1.1.1.3:2182,1.1.1.4:2183 zookeeper.connection.timeout.ms=6000 }} 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.. Please help me this is the third time in last three Saturdays i faced the similar issue. Courtesy Abhi !wq -- This message was sent by Atlassian JIRA (v6.4.14#64029)
