I am running confluent platform (version 6.1.1). I deploy the following components: 3 Brokers, 3 ZK, Schema Registry, 3 Kafka Connect, KSQL and Confluent Control Center (CCC).
The CCC has entered into a failed state and I have difficulties to bring it back.
To make things cleaner, I have created another EC2 instance (m4.2xlarge) where I configured new CCC with the aim to connect it to the current cluster. New CCC has exactly the same configuration as the failed one, but with a different confluent.controlcenter.id.
I start the CCC and it is running. I can access the CCC UI but it is not working properly: the pages are loading too long, it keeps showing the changing state of the connect cluster (sometimes healthy, sometimes not), it keeps showing the changing state of the brokers (sometimes healthy, sometimes not)
For example it looks like this (see screenshots):
After running certain amount of time, it is automatically restarted and keeps restarting every 5-7 minutes.
When it is started, I see a bunch of new topics created in the Kafka cluster.
After that in the control-center.log I see :

Running Kafka Connect via this repo https://github.com/entechlog/kafka-examples/tree/master/kafka-connect-standalone except I have added extra configs for AWS MSK IAM authentication. I've also updated the .env file to use different variables, like the AWS MSK IAM jar file, AWS key/secret key credentials, and a few other minor things. Note that this repo runs in standalone mode, but I have updated the launch shell script to run in distributed mode: exec connect-distributed /etc/"${COMPONENT}"/"${COMPONENT}".properties. But I have NOT created a file called kafka-connect.properties.template because when I do, I get a whole host of errors like Missing required configuration "group.id" which has no default value. which makes no sense to me as I can see it in the docker-compose.yml file.
My goal is to get data from a third party Kafka cluster into BigQuery.
When I run my docker-compose file, I see no errors, a few warnings, but nothing that stands out to me. I get a lot of warnings like this: [2021-12-14 01:57:37,917] WARN The configuration 'camelcase.default.dataset' was supplied but isn't a known config. (org.apache.kafka.clients.consumer.ConsumerConfig:380), and this dataset is required to send data to BigQuery. Not making sense why things like dataset are not being used.

I am trying to consume records using application written in spring-kafka. I am facing very unique condition and not able to understand why this is happening ?
My consumer application is running with 2 concurrency meaning 2 consumer thread subscribed to topic having two partitions.I am consuming records and placing it into table using upsert with offset, partitions and insert timestamp.
I am seeing duplicate values with same offset and partition in the table which should not occur. There is no difference in the timestamp value, means insert occurred at the same time. I am not sure how is it possible? I don't see any issue in the log as well. I am not sure what is happening at the Producer end but we can't have 2 values at the same offset anyway, so not sure whether this is an issue at consumer end of producer end.Any suggestion or thought which would help me to triage this issue?
Kafka log :
I don't see anything unusual in the log as well.

I am trying to set up ELK stack with one of my Logstash filter on my local machine.
I have an input file that comes into a kafka queue that is parse by my filter. Which outputs to elasticsearch. When I run my test.sh that runs the logstash filter on the input file, this is the resulting errors in logstash --debug
I am not sure what this error could be, all of my settings are localhost and default ports. Any guidance as this error does not tell me much.

Make sure the bootstrap server is localhost:9092, in your case
I followed the below tutorial to setup nifi cluster. Performed everything as mentioned, but receiving the below error.

But the zookeeper was unable to elect a leader and getting the following error message.
