            kafka issue while connecting to zookeeper (kubernetes-kafka:1.0-10.2.1)

            Your Kafka and Zookeeper deployments are running in the kaf namespace according to your screenshots, presumably you have set this up manually and applied the configurations while in that namespace? Neither the Kafka or Zookeeper YAML files explicitly state a namespace in metadata, so will be deployed to the active namespace when created.

            Anyway, the Kafka deployment YAML you have is hardcoded to assume Zookeeper is setup in the default namespace, with the following line:

            Thanks all.

            I was using an older Kafka version.

            I upgraded Kafka in the cluster from kafka_2.12-1.1.0 to the latest stable version kafka_2.12-2.7.0. I also upgraded zookeeper from zookeeper-3.4.6 to apache-zookeeper-3.6.2-bin version.

            In addition in the run file I added the following:



            Kafka stream: Monthly time windows
            Asked 2020-Dec-09 at 09:37

            Based on this example (, I would like to create a Monthly time windows. The problem is the size method which I don't know the size since every month have a different size.

            For more context, I want to count each unique user who made a transaction over a month based on userId.

            The problem is the size method which I don't know the size since every month have a different size.

            You can convert months to days and then add it. You will also need to take care of checking leap year.

            kafka-streams: retry complete message join if single element is missing
            Asked 2020-Jul-23 at 09:45

            I'm performing a message enrichement through a KStream-KTable left join using the kafka-streams DSL. Everything worked smoothly except for a subtle problem.

            In the current architecture we receive in a topic (placements, the KStream) some messages that needs to be enriched with the data from a compacted topic (descriptions, the KTable). The messages are something like:



            Answered 2020-Jul-23 at 09:45

            After careful analysis of the custom join example, the solution is to slightly change its logic.

            Below an excerpt from the example:



            Cannot run Kafka on mac
            Asked 2020-Feb-25 at 11:37

            I am very new to using Microservices and having trouble running Kafka after I have started zookeeper.

            Zookeeper starts fine but when I try to start my Kafka server it throws an error.

            I have searched on google to try and solve my problem but its quite overwhelming, as I am not sure what all these different config files mean/do.

            I have tried by enabling listeners=PLAINTEXT://:9092 in server settings but it doesn't work.

            I have also tried to un and reinstalled Kafka and ZooKeeper but I still get the same error.



            Answered 2020-Feb-25 at 11:37

            The cause of the problem is shown in this message:


            The Cluster ID S4SZ31nVRTCQ4uwRJ9_7mg

            doesn't match stored clusterId Some(Y_mQi4q4TSuhlWdx4DHiaQ)


            The broker is trying to join the wrong cluster.
            Configured zookeeper.connect may be wrong.

            The above problem occurs when a new instance of Kafka is being started up on data storage created by another kafka server. Kafka stores its messages in 'log' files.

            How to fix the problem?

            The problem can be fixed in these steps:

            1. Shutdown both Kafka and Zookeeper
            2. If required, take backup of the existing logs of Kafka and Zookeeper
            3. Delete the log directories of both Kafka and Zookeeper
            4. Restart Zookeeper and Kafka
