> Most parse errors in the JSON parsing SQL functions (e.g. json_tuple, get_json_object) will return a null(s) if the JSON is badly formed. However, if Jackson determines that the string includes invalid characters it will throw an exception (java.io.CharConversionException: Invalid UTF-32 character) that Spark does not catch. This creates a robustness problem in that these functions cannot be used at all when there may be dirty data as these exceptions will kill the jobs.
