WebNov 19, 2024 · Recursive value xxx needs type in Scala scala type-inference 33,881 Solution 1 To infer the type of y, the compiler must first determine the type of value on the right side of assignment. While evaluating right hand's type, it encounters reference to variable y which is (at this moment) still of unknown type. WebSpark may blindly pass null to the Scala closure with primitive-type argument, and the closure will see the default value of the Java type for the null argument, e.g. udf ( (x: Int) => x, IntegerType), the result is 0 for null input. To get rid of this error, you could:
