You have practiced to read and write files in AWS S3 from your Pyspark Container. Text files are very simple and convenient to load from and save to Spark applications.When we load a single text file as an RDD, then each input line becomes an element in the RDD.It can load multiple whole text files at the same time into a pair of RDD elements, with the key being the name given and the value of the contents of each file format specified. textFile() and wholeTextFile() returns an error when it finds a nested folder hence, first using scala, Java, Python languages create a file path list by traversing all nested folders and pass all file names with comma separator in order to create a single RDD. But the leading underscore shows clearly that this is a bad idea. Here, we have looked at how we can access data residing in one of the data silos and be able to read the data stored in a s3 bucket, up to a granularity of a folder level and prepare the data in a dataframe structure for consuming it for more deeper advanced analytics use cases.
