Question
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)
Options
- AThe years list should be wrapped in another list like List(years) to make clear that it is a column
- BThe data type is not specified - the second argument to createDataset should be IntegerType.
- CThere is no operation createDataset - the createDataFrame operation should be used instead.
- DThe result of the above is a Dataset rather than a DataFrame - the toDF operation must be called
- EThe column name must be specified as the second argument to createDataset.
