Fallback FitOperation type class implementation which is used if no other FitOperation with the right input types could be found in the scope of the implementing class.
Fallback FitOperation type class implementation which is used if no other FitOperation with the right input types could be found in the scope of the implementing class. The fallback FitOperation makes the system fail in the pre-flight phase by throwing a RuntimeException which states the reason for the failure. Usually the error is a missing FitOperation implementation for the input types or the wrong chaining of pipeline operators which have incompatible input/output types.

Fallback PredictDataSetOperation if a Predictor is called with a not supported input data type.
Fallback PredictDataSetOperation if a Predictor is called with a not supported input data type. The fallback PredictDataSetOperation lets the system fail with a RuntimeException stating which input and output data types were inferred but for which no PredictDataSetOperation could be found.

Fallback TransformDataSetOperation for Transformer which do not support the input or output type with which they are called.
Fallback TransformDataSetOperation for Transformer which do not support the input or output type with which they are called. This is usually the case if pipeline operators are chained which have incompatible input/output types. In order to detect these failures, the fallback TransformDataSetOperation throws a RuntimeException with the corresponding input/output types. Consequently, a wrong pipeline will be detected at pre-flight phase of Flink and thus prior to execution time.
