I am working on debezium mongodb source connector. Can I run connector in local machine in distributed mode by giving kafka bootstrap server address as remote machine (deployed in Kubernetes) and remote MongoDB url?
I tried this and I see connector starts successfully, no errors, just few warnings but no data is flowing from mongodb.
Using below command to run connector
./bin/connect-distributed ./etc/schema-registry/connect-avro-distributed.properties ./etc/kafka/connect-mongodb-source.properties
If not how else can I achieve this, I donot want to install local kafka or mondoDB as most of the tutorial suggest. I want to use our test servers for this.
Followed below tutorial for this : https://medium.com/tech-that-works/cloud-kafka-connector-for-mongodb-source-8b525b779772
Below are more details for the issue Connector works fine, I see below lines at the end of connector log
INFO [Worker clientId=connect-1, groupId=connect-cluster] Starting connectors and tasks using config offset -1 (org.apache.kafka.connect.runtime.distributed.DistributedHerder:1000)
] INFO [Worker clientId=connect-1, groupId=connect-cluster] Finished starting connectors and tasks (org.apache.kafka.connect.runtime.distributed.DistributedHerder:1021)
I have also defined MongoDB config in /etc/kafka/connect-mongodb-source.properties as follows
name=mongodb-source-connector
connector.class=io.debezium.connector.mongodb.MongoDbConnector
mongodb.hosts=/remoteserveraddress:27017
mongodb.name=mongo_conn
initial.sync.max.threads=1
tasks.max=1
But Data is not flowing between MongoDB and Kafka. I have also posted saperate question for this Kafka-MongoDB Debezium Connector : distributed mode
Any pointers are appriciated
connect-distributed only accepts a single property file.
You must use the REST API to configure Kafka Connect in Distributed mode.
https://docs.confluent.io/current/connect/references/restapi.html
Note: by default, the consumer will read the latest data off the topic, not existing data.
You would add this to the connect-avro-distributed.properties to fix it
consumer.auto.offset.reset=earliest
