You would like to compute the rely of each and every word from the textual content file. Here's tips on how to execute this computation with Spark RDDs:
Text file RDDs is usually developed working with SparkContext?�s textFile method. This method will take a URI to the file (possibly a local path to the machine, or simply a hdfs://, s3a://, and so on URI) and reads it as a group of strains. Here's an case in point invocation:
