  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.

  Spark 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 ...

  GraphX扩展了Spark RDD，引入一个新的Graph抽象概念，Graph是一个有向多重图，每个点和边都有自己的属性。 GraphX提供了一组基本的操作符来支持图计算，如subgraph、joinVertices和aggregateMessages等，GraphX还包含了优化过的Pregel API和一些图算法来简化图的分析工作。

  We have implemented LDA in Scala using Spark MLlib. We have written the program in such a way that it could be launched in both Spark standalone mode as well as cluster mode. Spark standalone mode supports 100 to 200 iterations of LDA with the available computational resources.

  distData: spark.RDD[Int] = spark.ParallelCollection@10d13e3e. Once created, the distributed dataset (distData here) can be operated on in parallel. For example, we might call distData.reduce(_ + _) to add up the elements of the array. We describe operations on distributed datasets later on.
