Description

The Scala code examples for the UDF type inference annotations are not correct.

For example: the following FunctionHint annotation

@FunctionHint(
  input = Array(@DataTypeHint("INT"), @DataTypeHint("INT")),
  output = @DataTypeHint("INT")
)

needs to be changed to

@FunctionHint(
  input = Array(new DataTypeHint("INT"), new DataTypeHint("INT")),
  output = new DataTypeHint("INT")
)
