Câu 63: Databricks Certified Associate Developer for Apache Spark

The code block shown below contains an error. The code block intended to create a single-column DataFrame from Scala List years which is made up of integers. Identify the error. Code block:spark.createDataset(years)

1. A. The years list should be wrapped in another list like List(years) to make clear that it is a column rather than a row.
2. B. The data type is not specified – the second argument to createDataset should be IntegerType.
3. C. There is no operation createDataset – the createDataFrame operation should be used instead.
4. D. The result of the above is a Dataset rather than a DataFrame – the toDF operation must be called at the end. — đáp án hiện tại
