Some of the different rdd generated in spark drink the logic of the user explicitly, for example, the map operation generates Mappartitionsrdd, and the RDD is the spark framework that helps us implicitly generate the For example, Reducebykey

Spark checkpoint by writing the RDD to disk as a checkpoint, spark lineage fault-tolerant auxiliary, lineage too long can cause fault-tolerant cost is too high, this time in the middle stage to do a checkpoint fault tolerance, if there is a problem

Sparkcontext is the interface between the user program and Spark, which is responsible for connecting to the spark cluster and requesting computing resources based on system default configuration and user settings to complete the creation of the RDD.
