Debezium connector mysql task failed

noname · 24 January 2023 14:05

Started the docker containers (cp-kafka-connect-base:7.0.1) and installed the self-managed connector (debezium-connector-mysql:latest).
Docker containers works good.
When I am trying to configure the connector configuration as below

{
“name”: “MySqlConnectorConnector_0”,
“config”: {
“database.history.consumer.sasl.jaas.config”: “org.apache.kafka.common.security.plain.PlainLoginModule”,
“database.history.kafka.topic”: “pageviews”,

“database.history.kafka.bootstrap.servers”: “local_IP:9092”,
“database.server.name”: “prod”,
“database.history.consumer.sasl.mechanism”: “PLAIN”,
“name”: “MySqlConnectorConnector_0”,
“connector.class”: “io.debezium.connector.mysql.MySqlConnector”,

}
}

Also added properties from this post Debezium mysql task failed - #2 by esquare666
but nothing

hey @noname

broker is up and running?
seems its not reachable from
the kafka connect container.

best,
michael

noname · 24 January 2023 19:58

Thank you for answer. Yes broker is up and running and i did not see any errors in brokers log.

esquare666 · 24 January 2023 20:26

I dont have full details of your env setup. Not sure where the kafka broker is up and running. What is the IP address of “local_IP” hostname.

Please use same broker details (either the variable CONNECT_BOOTSTRAP_SERVERS (if you are using env variable) or the value of bootstrap.servers (if you use property file)) what is configured in connect docker container

noname · 24 January 2023 20:30

All config parameters are also in default. Also added docker network to all containers to eliminate the problem of accessibility over the network. Added docker volume to broker.

volumes:
      - broker:/etc/kafka

Can i try Scenario 3: Kafka in Docker Compose from this documentation?

I’m tried change config. With this one i had “Failed to construct kafka producer”.

{
  "name": "MySqlConnectorConnector_0",
  "config": {
    "database.history.consumer.sasl.jaas.config": "org.apache.kafka.common.security.plain.PlainLoginModule",
    "database.history.consumer.security.protocol": "SASL_SSL",
    "database.history.consumer.ssl.endpoint.identification.algorithm": "https",
    "topic.prefix": "test2",
    "schema.history.internal.kafka.topic": "PLAIN",
    "database.whitelist": "database-test",
    "database.history.producer.sasl.mechanism": "PLAIN",
    "database.history.producer.sasl.jaas.config": "org.apache.kafka.common.security.plain.PlainLoginModule",
    "database.history.producer.ssl.endpoint.identification.algorithm": "https",
    "database.history.producer.security.protocol": "SASL_SSL",
    "schema.history.internal.kafka.bootstrap.servers": "51.59.201.169:9092",
    "database.history.consumer.sasl.mechanism": "PLAIN",
    "name": "MySqlConnectorConnector_0",
    "connector.class": "io.debezium.connector.mysql.MySqlConnector",
    "tasks.max": "1",
    "errors.log.enable": "true",
    "errors.log.include.messages": "true",
    "database.hostname": "database-test.cvkqon73ntcl.eu-central-1.rds.amazonaws.com",
    "database.port": "3306",
    "database.user": "admin",
    "database.password": "**********",
    "database.server.name": "database-test.cvkqon73ntcl.eu-central-1.rds.amazonaws.com",
    "database.server.id": "11",
    "database.ssl.mode": "disabled",
    "connect.keep.alive": "true",
    "database.history.kafka.bootstrap.servers": "51.59.201.169:9092",
    "database.history.kafka.topic": "pageviews",
    "include.schema.changes": "true",
    "inconsistent.schema.handling.mode": "skip"
  }
}

Can you please tell what base parameters should be in this config to run this normally?

it might be related to a proper routing/hostname resolution.

how does your docker-compose.yml look like?
especially the CONNECT_BOOTSTRAP_SERVERS @esquare666 mentioned.

Best,
michael
