Modern Spark operates by a design choice to separate storage and compute. So saving a csv to the river's local disk doesn't make sense for a few reasons:the worker nodes don't have access to the driver's disk. They would need to send the data over to...
you can use code provided by Jose in %python by just removing val If you know the schema, it is better to avoid schema inference and pass it to DataFrameReader. Exxample if you have three columns - integer, double and string:from pyspark.sql.types im...
