Confluent replicator issue - apache-kafka

Question

I am trying to push topic data from one Kafka cluster to another (Both on-prem linux). For this, I am using Confluent kafka-connect-replicator.
Using - confluent enterprise 5.0
Following this doc -
https://docs.confluent.io/current/connect/kafka-connect-replicator/index.html#replicator-as-a-connector
I have already changed ports of zookeeper and broker to 2171 and 9082 resp. at source Kafka cluster.
Destination Kafka cluster is running on default ports.
My configuration files are :
/etc/kafka-connect-replicator/quickstart-replicator.properties
name=replicator-source
connector.class=io.confluent.connect.replicator.ReplicatorSourceConnector
key.converter=io.confluent.connect.replicator.util.ByteArrayConverter
value.converter=io.confluent.connect.replicator.util.ByteArrayConverter
header.converter=io.confluent.connect.replicator.util.ByteArrayConverter
tasks.max=4
src.kafka.bootstrap.servers=X.X.X.X:9082
src.zookeeper.connect=X.X.X.X:2171
dest.kafka.bootstrap.servers=Y.Y.Y.Y:9092
dest.zookeeper.connect=Y.Y.Y.Y:2181
confluent.topic.replication.factor=1
topic.whitelist=test-topic
topic.rename.format=${topic}.replica
topic.create.backoff.ms=10000
/etc/schema-registry/connect-avro-standalone.properties
bootstrap.servers=localhost:9082
key.converter=io.confluent.connect.avro.AvroConverter
key.converter.schema.registry.url=http://localhost:8081
value.converter=io.confluent.connect.avro.AvroConverter
value.converter.schema.registry.url=http://localhost:8081
internal.key.converter=org.apache.kafka.connect.json.JsonConverter
internal.value.converter=org.apache.kafka.connect.json.JsonConverter
internal.key.converter.schemas.enable=false
internal.value.converter.schemas.enable=false
offset.storage.file.filename=/data/kafka/connect.offsets
plugin.path=/usr/share/java
Run the replicator connector -
/usr/bin/connect-standalone /etc/schema-registry/connect-avro-standalone.properties /etc/kafka-connect-replicator/quickstart-replicator.properties
But when I run the replicator, it creates replica topic at destination cluster but if I produce messages, it doesn't show in the consumer at the destination cluster.
It also throws WARNs at the command prompt.

What am I missing? How can I replicate data to the other cluster broker?
thanks!
