The first time it is computed in an action, it will be kept in memory on the nodes. Spark’s cache is fault-tolerant – if any partition of an RDD is lost, it will automatically be recomputed using the transformations that originally created it....
Apache Spark can also be used to process or read simple to complex nested XML files into Spark DataFrame and writing it back to XML using DatabricksSpark XML API(spark-xml) library. In this article, I will explain how to read XML file with several options using the Scala example. Advertise...
