针对这个小案例, 我们问出互相关联但是又方向不同的五个问题

1.假设要针对整个网站的历史数据进行处理, 量有 1T, 如何处理?

放在集群中, 利用集群多台计算机来并行处理

2.如何放在集群中运行?

简单来讲, 并行计算就是同时使用多个计算资源解决一个问题, 有如下四个要点

• 要解决的问题必须可以分解为多个可以并发计算的部分
• 每个部分要可以在不同处理器上被同时执行
• 需要一个共享内存的机制
• 需要一个总体上的协作机制来进行调度

3.如果放在集群中的话, 可能要对整个计算任务进行分解, 如何分解?

概述

• 对于 HDFS 中的文件, 是分为不同的 Block 的
• 在进行计算的时候, 就可以按照 Block 来划分, 每一个 Block 对应一个不同的计算单元

扩展

• RDD 并没有真实的存放数据, 数据是从 HDFS 中读取的, 在计算的过程中读取即可
• RDD 至少是需要可以 分片 的, 因为HDFS中的文件就是分片的, RDD 分片的意义在于表示对源数据集每个分片的计算, RDD 可以分片也意味着 可以并行计算

4.移动数据不如移动计算是一个基础的优化, 如何做到?

每一个计算单元需要记录其存储单元的位置, 尽量调度过去

5.在集群中运行, 需要很多节点之间配合, 出错的概率也更高, 出错了怎么办?

RDD1 → RDD2 → RDD3 这个过程中, RDD2 出错了, 有两种办法可以解决

• 缓存 RDD2 的数据, 直接恢复 RDD2, 类似 HDFS 的备份机制
• 记录 RDD2 的依赖关系, 通过其父级的 RDD 来恢复 RDD2, 这种方式会少很多数据的交互和保存

如何通过父级 RDD 来恢复?

• 记录 RDD2 的父亲是 RDD1
• 记录 RDD2 的计算函数, 例如记录 RDD2 = RDD1.map(…​), map(…​) 就是计算函数
• 当 RDD2 计算出错的时候, 可以通过父级 RDD 和计算函数来恢复 RDD2

6.假如任务特别复杂, 流程特别长, 有很多 RDD 之间有依赖关系, 如何优化?

上面提到了可以使用依赖关系来进行容错, 但是如果依赖关系特别长的时候, 这种方式其实也比较低效, 这个时候就应该使用另外一种方式, 也就是记录数据集的状态

在 Spark 中有两个手段可以做到

• 缓存
• Checkpoint

再谈 RDD

目标

1. 理解 RDD 为什么会出现
2. 理解 RDD 的主要特点
3. 理解 RDD 的五大属性

RDD 为什么会出现?

在 RDD 出现之前, 当时 MapReduce 是比较主流的, 而 MapReduce 如何执行迭代计算的任务呢?

多个 MapReduce 任务之间没有基于内存的数据共享方式, 只能通过磁盘来进行共享

这种方式明显比较低效

RDD 如何解决迭代计算非常低效的问题呢?

在 Spark 中, 其实最终 Job3 从逻辑上的计算过程是: Job3 = (Job1.map).filter, 整个过程是共享内存的, 而不需要将中间结果存放在可靠的分布式文件系统中

这种方式可以在保证容错的前提下, 提供更多的灵活, 更快的执行速度.

RDD 的特点

RDD 不仅是数据集, 也是编程模型
RDD 即是一种数据结构, 同时也提供了上层 API, 同时 RDD 的 API 和 Scala 中对集合运算的 API 非常类似, 同样也都是各种算子

RDD 的算子大致分为两类:

• Transformation 转换操作, 例如 map flatMap filter 等
• Action 动作操作, 例如 reduce collect show 等

执行 RDD 的时候, 在执行到转换操作的时候, 并不会立刻执行, 直到遇见了 Action 操作, 才会触发真正的执行, 这个特点叫做 惰性求值

RDD 可以分区

RDD 是一个分布式计算框架, 所以, 一定是要能够进行分区计算的, 只有分区了, 才能利用集群的并行计算能力

同时, RDD 不需要始终被具体化, 也就是说: RDD 中可以没有数据, 只要有足够的信息知道自己是从谁计算得来的就可以, 这是一种非常高效的容错方式

RDD 是只读的

RDD 是只读的, 不允许任何形式的修改. 虽说不能因为 RDD 和 HDFS 是只读的, 就认为分布式存储系统必须设计为只读的. 但是设计为只读的, 会显著降低问题的复杂度, 因为 RDD 需要可以容错, 可以惰性求值, 可以移动计算, 所以很难支持修改.

• RDD2 中可能没有数据, 只是保留了依赖关系和计算函数, 那修改啥?
• 如果因为支持修改, 而必须保存数据的话, 怎么容错?
• 如果允许修改, 如何定位要修改的那一行? RDD 的转换是粗粒度的, 也就是说, RDD 并不感知具体每一行在哪.

RDD 是可以容错的

RDD 的容错有两种方式

• 保存 RDD 之间的依赖关系, 以及计算函数, 出现错误重新计算
• 直接将 RDD 的数据存放在外部存储系统, 出现错误直接读取, Checkpoint

什么叫做弹性分布式数据集

分布式

• RDD 支持分区, 可以运行在集群中

弹性

• RDD 支持高效的容错
• RDD 中的数据即可以缓存在内存中, 也可以缓存在磁盘中, 也可以缓存在外部存储中

数据集

• RDD 可以不保存具体数据, 只保留创建自己的必备信息, 例如依赖和计算函数
• RDD 也可以缓存起来, 相当于存储具体数据

总结: RDD 的五大属性

首先整理一下上面所提到的 RDD 所要实现的功能:

• RDD 有分区
• RDD 要可以通过依赖关系和计算函数进行容错
• RDD 要针对数据本地性进行优化
• RDD 支持 MapReduce 形式的计算, 所以要能够对数据进行 Shuffled

对于 RDD 来说, 其中应该有什么内容呢? 如果站在 RDD 设计者的角度上, 这个类中, 至少需要什么属性?

• Partition List 分片列表, 记录 RDD 的分片, 可以在创建 RDD 的时候指定分区数目, 也可以通过算子来生成新的 RDD 从而改变分区数目
• Compute Function 为了实现容错, 需要记录 RDD 之间转换所执行的计算函数
• RDD Dependencies RDD 之间的依赖关系, 要在 RDD 中记录其上级 RDD 是谁, 从而实现容错和计算
• Partitioner 为了执行 Shuffled 操作, 必须要有一个函数用来计算数据应该发往哪个分区
• Preferred Location 优先位置, 为了实现数据本地性操作, 从而移动计算而不是移动存储, 需要记录每个 RDD 分区最好应该放置在什么位置
