WebSpecific to Scala, a list is a collection which contains immutable data, which means that once the list is created, then it can not be altered. In Scala, the list represents a linked list. In a Scala list, each element need not be of the same data type. The implementation of Scala lists uses a mutable state internally during the construction phase. WebScala, Java, Python and R examples are in the examples/src/main directory. To run one of the Java or Scala sample programs, use bin/run-example [params] in the top-level Spark directory. (Behind the scenes, this invokes the more general spark-submit script for launching applications). WebThe following commands are used to compile and execute this program.
