Xingcan Cui commented on FLINK-8538:
------------------------------------

BTW, it may not be a good idea to implement them in Java since the base classes 
(e.g.,
 {{ConnectorDescriptorValidator}} and {{ConnectorDescriptor}}) are all 
implemented in scala, which means the API contains lots of scala features 
(e.g., function parameter and scala collections). What do you think?

> Add a Kafka table source factory with JSON format support

> Similar to CSVTableSourceFactory a Kafka table source factory for JSON should 
> be added. This issue includes improving the existing JSON descriptor with 
> validation that can be used for other connectors as well. It is up for 
> discussion if we want to split the KafkaJsonTableSource into connector and 
> format such that we can reuse the format for other table sources as well.
