Text file RDDs might be created utilizing SparkContext?�s textFile process. This method can take a URI for your file (both a local route over the machine, or possibly a hdfs://, s3a://, etcetera URI) and reads it as a set of lines. Here's an instance invocation:
(RDD), which happens to be a group of factors partitioned across the nodes with the cluster that may be operated on in parallel. RDDs are created by starting by using a file in the Hadoop file process (or almost every other Hadoop-supported file method), or an present Scala collection in the driving force application, and transforming it.
