[All Certified Associate Developer for Apache Spark Questions]

The code block shown below contains an error. The code block is intended to read JSON at the file path filePath into a DataFrame with the specified schema schema. Identify the error.

Code block:

spark.read.schema("schema").format("json").load(filePath)

  • A. The schema operation from read takes a schema object rather than a string — the argument should be schema.
  • B. There is no load() operation for DataFrameReader — it should be replaced with the json() operation.
  • C. The spark.read operation should be followed by parentheses in order to return a DataFrameReader object.
  • D. There is no read property of spark — spark should be replaced with DataFrame.
  • E. The schema operation from read takes a column rather than a string — the argument should be col("schema").
