    Core Spark functionality.

    Core Spark functionality. org.apache.spark.SparkContext serves as the main entry point to Spark, while org.apache.spark.rdd.RDD is the data type representing a distributed collection, and provides most parallel operations.

    In addition, org.apache.spark.rdd.PairRDDFunctions contains operations available only on RDDs of key-value pairs, such as groupByKey and join; org.apache.spark.rdd.DoubleRDDFunctions contains operations available only on RDDs of Doubles; and org.apache.spark.rdd.SequenceFileRDDFunctions contains operations available on RDDs that can be saved as SequenceFiles. These operations are automatically available on any RDD of the right type (e.g. RDD[(Int, Int)] through implicit conversions.

    Java programmers should reference the org.apache.spark.api.java package for Spark programming APIs in Java.

    Classes and methods marked with Experimental are user-facing features which have not been officially adopted by the Spark project. These are subject to change or removal in minor releases.

    Classes and methods marked with Developer API are intended for advanced users want to extend Spark through lower level interfaces. These are subject to changes or removal in minor releases.

Type Members

  1. final class CalendarInterval extends Serializable with Comparable[CalendarInterval]

    The class representing calendar intervals.

    The class representing calendar intervals. The calendar interval is stored internally in three components:

    • an integer value representing the number of months in this interval,
    • an integer value representing the number of days in this interval,
    • a long value representing the number of microseconds in this interval.

    The months and days are not units of time with a constant length (unlike hours, seconds), so they are two separated fields from microseconds. One month may be equal to 28, 29, 30 or 31 days and one day may be equal to 23, 24 or 25 hours (daylight saving).
