Failed to start kafka server in Window [duplicate] - apache-kafka

This question already has answers here:
How to install Kafka on Windows?
(9 answers)
Closed 1 year ago.
I downloaded the kafka_2.13-3.0.0 in Window 10. I opened up CMD as admin. I was able to run zookeeper using the command bin\windows\zookeeper-server-start.bat config\zookeeper.properties. However, when i tried to start the kafka server with the following command
bin\windows\kafka-server-start.bat config\server.properties
, it gave me the following error" below. I am confused here because I can see the kafka-logs being created (see image below). Can someone help me out please ?

I also tried running icacls "C:\tmp\" /q /c /t /grant Users:F. I am still getting the same error.

It turns out that 3.0.0 has issues with Windows. I downgraded to 2.8.1 and things worked fine. I hate Windows.

Kafka issue with adding SASL security

I'm using Confluent Community 6.0.1. Three nodes Kafka cluster:
devKafka04: Kafka Broker1, Zookeeper 1
devKafka05: Kafka Broker2, Zookeeper 2
devKafka06: Kafka Broker3, Zookeeper 3
The SSL encryption is already working well on the Kafka Brokers.
I'd like to add SASL to enable mutual authentication between Kafka and Zookeeper.
I was following the Confluent document:
https://docs.confluent.io/platform/current/kafka/incremental-security-upgrade.html#adding-security-to-a-running-zk-cluster
[Updates] After I applied the changes, Zookeeper could not start on the secureclientPort. That's why the Kafka broker couldn't start. Here are the error log and docker compose configurations.
I'm wondering if there's something with the confluent zookeeper image.
Please help me out. Thanks.

Many Zookeeper instances were running earlier. I killed all the zookeeper and Brokers , restarted them again freshly . It is working fine now.

Cannot run Kafka on mac

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.

The cause of the problem is shown in this message:
kafka.common.InconsistentClusterIdException:
The Cluster ID S4SZ31nVRTCQ4uwRJ9_7mg
doesn't match stored clusterId Some(Y_mQi4q4TSuhlWdx4DHiaQ)
in meta.properties.
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:
Shutdown both Kafka and Zookeeper
If required, take backup of the existing logs of Kafka and Zookeeper
Delete the log directories of both Kafka and Zookeeper
Restart Zookeeper and Kafka

Zookeeper accepting and closing unexpected socket connection even before Kafka is run

Zookeeper is accepting a socket connection from 50167(in my case) and then closed it.

Due to this, Kafka server is also failing to run. Any solution will be helpful.
After, I deleted the old logs at location:
i.e. folders kafka_2.11-0.11.0.0kafka-logs & kafka_2.11-0.11.0.0zookeeper-data, the server started fine.

I verified the topic and it is present. What is going wrong. Please help.
I had the same problem and here is how I fixed it:
1) Stop all Kafka and Zookeeper processes
ps -aux | grep zoo
ps -aux | grep kafka
(then proceed to kill all process ids from above jobs)
2) Run zookeeper
<kafka_dir>/bin/zookeeper-server-start.sh ../config/zookeeper.properties
3) Run kafka server
<kafka_dir>/bin/kafka-server-start.sh ../config/server.properties
Try -> telnet 192.168.33.10 2181
If the telnet fails, then the issue is due to below reason.
Zookeeper Server NRPE iptables chain does not appear to a have a default accept rule.
Unless you just want your own iptables chain for NRPE, you could use:
iptables -I INPUT -s 0/0 -p tcp --dport 2181 -j ACCEPT
This solves the issue.
You can try the follwoing to see if it helps ..
1) Make sure the zookeeper is up and running, try to connect to it using the zkCli client .
2) append --from-beginning at the end of your command to see if you get any diifference in the output , so the command should be changed to :
$KAFKA_HOME/bin/kafka-console-consumer.sh --zookeeper xxx.xx.xx.xxx:2181 --topic topic-3 --from-beginning
In my case it was already connected to the host from which I was trying, so it was not able to make any new connection to the host. I had to change the config: maxClientCnxns so that it was able to make more connection to that host. More details here.
