Q54 Single choice

The code block displayed below contains an error. The code block should write DataFrame transactionsDf as a parquet file to location filePath after partitioning it on column storeId.

Find the error.

Code block:

transactionsDf.write.partitionOn("storeId").parquet(filePath)

A
The partitioning column as well as the file path should be passed to the write() method of DataFrame transactionsDf directly and not as appended commands as in the code block.
B
The partitionOn method should be called before the write method.
C
The operator should use the mode() option to configure the DataFrameWriter so that it replaces any existing files at location filePath.
D
Column storeId should be wrapped in a col() operator.
E
No method partitionOn() exists for the DataFrame class, partitionBy() should be used instead.
