Expression Transformation on the Databricks Spark Engine

Mapping validation fails in the following situations:

The transformation contains stateful variable ports.

The transformation contains unsupported functions in an expression.

If an expression results in numerical errors, such as division by zero or SQRT of a negative number, it returns a null value and rows do not appear in the output. In the native environment, the expression returns an infinite or an NaN value.
