    Description

      Description of problem:

      -Kafka: SSL handshake failed : unexpected eof while reading Error in Vector Collector.
      -Logforwarding to kafka destination is not working with Vector Collector.

      Version-Release number of selected component (if applicable):

      How reproducible:

      It can be reproduced:

      Steps to Reproduce:

      1. Install RHOCP Cluster . (4.12, 4.13, 4.14)
      2. Install Cluster Logging Operator 5.8.3
      3. Create a ClusterLogging instance using Vector as collector.
      4. Create a secret and a CLF instance with Kafka brokers:
      apiVersion: logging.openshift.io/v1
kind: ClusterLogForwarder
metadata:
  name: instance
  namespace: openshift-logging
spec:
  outputs:
    - name: kafka
      type: "kafka"
      secret:
        name: kafka-secret
      kafka:
        brokers:
          - tcp://XXXXX1:9093
          - tcp://XXXXX2:9093
          - tcp://XXXXX3:9093
        topic: XXXX-demo
  pipelines:
    - name: XXXX-demo
      inputRefs:
        - XXXX-demo
      outputRefs:
        - kafka

            5. Check the logs of collector pods:

      2024-02-17T10:02:51.987537Z ERROR librdkafka: librdkafka: FAIL [thrd:sasl_ssl://KAFKA_BROKER_IP:9093/bootstrap]: sasl_ssl://KAFKA_BROKER_IP:9093/bootstrap: SSL handshake failed: error:0A000126:SSL routines::unexpected eof while reading (after 100ms in state SSL_HANDSHAKE, 13 identical error(s) suppressed)    
2024-02-17T10:02:51.987595Z ERROR rdkafka::client: librdkafka: Global error: SSL (Local: SSL error): sasl_ssl://KAFKA_BROKER_IP:9093/bootstrap: SSL handshake failed: error:0A000126:SSL routines::unexpected eof while reading (after 100ms in state SSL_HANDSHAKE, 13 identical error(s) suppressed) 

      Actual results:

      Collector pods are streaming above error logs.
      Logs are not getting forwarded to Kafka destination.
      Tried with a single kafka broker as well, but received same error logs.

      Expected results:

      ClusterLogFowarder needs to forward logs to Kafka destination.

      Additional info:

      • Same configuration is working fine with Fluentd as collector.
      • Facing issue while using Vector as collector.
      • Tried with a single kafka broker as well, but received same error logs.
