> Key: KAFKA-5204

> Project: Kafka
> Issue Type: Bug
> Components: KafkaConnect

> Reporter: Konstantine Karantasis

> Priority: Major

> Currently Connect will accept to instantiate connectors that extend the {{Connector}} abstract class but not one of its subclasses, {{SourceConnector}} or {{SinkConnector}}.
> However, in distributed mode as well as in REST, Connect assumes in a few places that there are only two types of connectors, sinks or sources. Based on this assumption it checks the type dynamically, and if it is not a sink it treats it as a source (by constructing the corresponding configs).
> A connector that implements only the {{Connector}} abstract class does not fit into this classification. Therefore a validation needs to take place early, during the instantiation of the {{Connector}} object.
