KAFKA-4837: Fix class name comparison in connector-plugins REST endpoint

> Key: KAFKA-4837
> URL: https://issues.apache.org/jira/browse/KAFKA-4837
> Project: Kafka
> Issue Type: Bug
> Components: KafkaConnect
> Affects Versions: 0.10.2.0

> A validation check in Connect's REST API that was added to validate that the
> connector class name in the config matches the connector class name in the
> request's URL is too strict by not considering both the simple and the
> canonical name of the connector class. For instance, the following example
> request:
> {code}
> PUT /connector-plugins/FileStreamSinkConnector/config/validate/ HTTP/1.1
> Host: connect.example.com
> Accept: application/json
> {
> "connector.class":
> "org.apache.kafka.connect.file.FileStreamSinkConnector",
> "tasks.max": "1",
> "topics": "test-topic"
> }
> {code}
> returns a "Bad Request" response with error code "400".
> Currently the reasonable workaround is to exactly match the connector class
> name in both places. The following will work:
> {code}
> PUT
> /connector-plugins/"org.apache.kafka.connect.file.FileStreamSinkConnector/config/validate/
> HTTP/1.1
> Host: connect.example.com
> Accept: application/json
> {
> "connector.class":
> "org.apache.kafka.connect.file.FileStreamSinkConnector",
> "tasks.max": "1",
> "topics": "test-topic"
> }
> {code}
> However, this is not flexible enough and also breaks several examples in
> documentation. Validation should take into account both simple and canonical
> class names.
