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.

trait ProtobufSerDe[T] extends AnyRef
:: DeveloperApi :: ProtobufSerDe used to represent the API for serialize and deserialize of Protobuf data related to UI.
:: DeveloperApi :: ProtobufSerDe used to represent the API for serialize and deserialize of Protobuf data related to UI. The subclass should implement this trait and register itself to org.apache.spark.status.protobuf.ProtobufSerDe so that KVStoreProtobufSerializer can use ServiceLoader to load and use them.
