In spark dataFrame, how to handle corrupted record?. Actually, I am looking for the corrupted record should persist to another file for later review. Mode - DROPMALFORMED option will drop corrupted record from the dataset. it will help.

val data = sparkSession.read

                       .option("mode", "DROPMALFORMED")

                       .json("file:///C:/finances.json")

If you want to persist corrupted records then you can filter those out into another dataframe and write it to file.

The catch here is to use PERMISSIVE(default) and not DROPMALFORMED mode as it would drop the corrupted records you wish to capture.

PERMISSIVE: tries to parse all lines: nulls are inserted for missing tokens and extra tokens are ignored.

Then, depending upon your clause of corruptness, you can filter the rows for null values.
