Setting mirror maker 2 using kafka connect rest api put method not allowed - apache-kafka

Question

I am trying to do the setup for mirror maker 2 using my current connect cluster.
Based on this documentation it can be done via connect rest api.
https://cwiki.apache.org/confluence/display/KAFKA/KIP-382%3A+MirrorMaker+2.0#KIP-382:MirrorMaker2.0-RunningMirrorMakerinaConnectcluster
I followed the sample sending this PUT request :
PUT /connectors/us-west-source/config HTTP/1.1
{
"name": "us-west-source",
"connector.class": "org.apache.kafka.connect.mirror.MirrorSourceConnector",
"source.cluster.alias": "us-west",
"target.cluster.alias": "us-east",
"source.cluster.bootstrap.servers": "us-west-host1:9091",
"topics": ".*"
}
but i am getting a method not allowed response error response.
{
"error_code": 405,
"message": "HTTP 405 Method Not Allowed"
}
The api looks ok if I do a simple GET from the / , returning the version
{
"version": "2.1.0-cp1",
"commit": "bda8715f42a1a3db",
"kafka_cluster_id": "VBo-j1OAQZSN8tO4lMJ0Gg"
}

the PUT method doesnt work, using POST works as the api's documentation shows:
https://docs.confluent.io/current/connect/references/restapi.html#get--connectors
Remove the name of the connector from the url as #cricket_007 suggested, and wrap the config with new element like this:
curl --noproxy "*" -XPOST -H 'Content-Type: application/json' -H 'Accept: application/json' http://localhost:8083/connectors -d'{
"name": "dc-west-source",
"config": {
"connector.class": "org.apache.kafka.connect.mirror.MirrorSourceConnector",
"source.cluster.alias": "dc-west",
"target.cluster.alias": "dc-east",
"source.cluster.bootstrap.servers": "dc-west-cp-kafka-0.domain:32721,dc-west-cp-kafka-1.domain:32722,dc-west-cp-kafka-2.dc.domain:32723",
"topics": ".*"
}
}
