What are you using for storing data in those subscriptions? Datalake or
Blobs? There is Azure Data Factory already available that can do copy
between these cloud storage without having to go through spark

shouldn't this be just -
df = spark.read.csv('out/df_in.csv')
sparkSession itself is in entry point to dataframes and SQL functionality .

I dont agree with above , "Learning Spark" book was definitely stepping
stone for me. All the basics that one beginner can/will need is covered in
very easy to understand format with examples. Great book! highly
You can use
-
start_date_test2.holiday.getItem[0]
I would highly suggest you to look at latest documentation -

Hi Afshin,
If you need to associate header information from 2nd file to first one i.e.
, you can do that with specifying custom schema. Below is example from
spark-csv package. As you can guess, you will have to do some
pre-processing to create customSchema by first reading second file .
val c
Can be as simple as -
from pyspark.sql.functions import split
flight.withColumn('hour',split(flight.duration,'h').getItem(0))
