If this input stream is not supported by real time mode, can we possibly test supported source in Python test?

The code change looks okay. Only wondering if we can add a supported case in Python test.

@viirya thank you for the review. The issue with that is currently no RTM supported sources can be used in pyspark. There is no memory source equivalent in python and using Kafka would require us to start a kafka cluster via docker and I had limited success with at via: In my follow up PR to this I will probably convert the socket source to support RTM and use that to test. |
