> 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.
