I have a column of dates (date type), just trying to find the nearest
holiday of the date. Anyone has any idea what went wrong below?
start_date_test = flight3.select("start_date").distinct()
start_date_test.show()
holidays = ['2017-09-01', '2017-10-01']
+----------+
|start_date|

index = spark.sparkContext.broadcast(sorted(holidays))
def nearest_holiday(date):
last_holiday = index.value[0]
for next_holiday in index.value:
if next_holiday >= date:
break
last_holiday = next_holiday
