Spark 的主要抽象是分布式的元素集合（distributed collection of items），称为RDD（Resilient Distributed Dataset，弹性分布式数据集），它可被分发到集群各个节点上，进行并行操作。RDDs 可以通过 Hadoop InputFormats 创建（如 HDFS），或者从其他 RDDs 转化而来。

Using a special framework with Python allows for parallel processing of data. PySpark (a Python framework for Apache Spark) breaks up data into separate “RDD” (Resilient Distributed Dataset) files that can be processed in parallel. These RDD files are manipulated through functional programming and have a unique fault tolerance.

Apache Spark [2] is an open source platform for scalable MapReduce computing on clusters. The role of the Spark platform is to tackling the volume, velocity, and volatility aspects of MBD. Essentially, the Spark engine tackles the volume aspect by parallelizing the learning task into many sub-tasks and each task performed on a small partition ...

The main abstraction Spark provides is a resilient distributed dataset (RDD), which is a collection of elements partitioned across the nodes of the cluster that can be operated on in parallel. RDDs are created by starting with a file in the Hadoop file system (or any other Hadoop-supported file system), or an existing Scala collection in the ...
