The main abstraction in Spark, is resilient distributed dataset (RDD), which represents a read-only collection of objects partitioned across a set of machines that can be rebuilt if a partition is lost. Users can explicitly cache an RDD in memory across different machines and reuse it in multiple MapReduce-like parallel operations.

就像RDD，如果某个主机出现异常，这个主机上的图分区是可以在另一台健康的主机上重新创建的。从逻辑上看，属性图对应于两个类型化集合（RDD），分别是顶点和边的属性集。相应的，图类（class）包含用于访问顶点和边的成员变量： class Graph[VD, ED]

Resilient Distributed Datasets (RDD) is a fundamental data structure of Spark. It is an immutable distributed collection of objects. Each dataset in RDD is divided into logical partitions, which may be computed on different nodes of the cluster. RDDs can contain any type of Python, Java, or Scala objects, including user-defined classes.

Unsupervised learning models in the form of dimensionality reduction.Dimensionality reduction does not focus on making predictions. Instead, it tries to take a set of input data with a feature dimension D (that is, the length of our feature vector), and extracts a representation of the data of dimension k, where k is usually significantly smaller than D.
