Hi Brijesh, i have a doubt. when i run " bin/kafka-server-start.sh config/server.properties " It says "Classpath is empty. Please build the project first" . Please help me out. zookeeper is running fine. issue with kafka.
i understood the concept but : Producer produced the data to a topic And then Consumer, consumed the data from that topic. So where this consumed data sits in the Kafka cluster ? And when what happens to the created topic which is there in the Kafka broker ? It'll just sit there and deleted when it hits the retention period?
Messages stay within persistence layer of Kafka cluster until they hit the retention threshold. on the other hand, Topics and partitions stay forever until someone manually deletes them
I had followed the same steps to setup kafka broker on three different node/vm with different IPs. But as I start all three broker I get the following error java.io.IOException: Connection to server2-Ip:9092 (id: 2 rack: null) failed. Note in my ubuntu server the firewall is inactive.
koi dikhawa nhi, koi fake accent nhi, koi criticism nhi. This is what an ideal teacher is expected of. Brijesh Sir thanks for this tutorial. I am planning for a switch and I know this tutorial will play a crucial role in my goal achievement.
In a Kafka cluster, the group coordinator is responsible for managing consumer group membership and assigning partitions to consumers. If a particular coordinator is down, it should automatically be replaced by another broker in the cluster to ensure high availability and fault tolerance? in my case If a particular coordinator is down, then consumer not join other orordinator, getting error "No active consumer" Please help how to solve this problem.
