CORBA（CommonObjectRequestBrokerArchitecture,公共对象请求代理体系结构）是由OMG（对象管理组织，ObjectManagementGroup）提出的应用软件体系结构和对象技术规范。
其核心是一套标准的语言、接口和协议，以支持异构分布应用程序间的互操作性及独立于平台和编程语言的对象重用。

本文主要讨论ApacheSpark的设计与实现，重点关注其设计思想、运行原理、实现架构及性能调优，附带讨论与HadoopMapReduce在设计与实现上的区别。
不喜欢将该文档称之为“源码分析”，因为本文的主要目的不是去解读实现代码，而是尽量有逻辑地，从设计与实现原理的角度，来理解job从产生到执行完成的整个过程，进而去理解整个系统。
讨论系统的设计与实现有很多方法，本文选择问题驱动的方式，一开始引入问题，然后分问题逐步深入。
从一个典型的job例子入手，逐渐讨论job生成及执行过程中所需要的系统功能支持，然后有选择地深入讨论一些功能模块的设计原理与实现方式。
也许这样的方式比一开始就分模块讨论更有主线。
本文档面向的是希望对Spark设计与实现机制，以及大数据分布式处理框架深入了解的Geeks。
因为Spark社区很活跃，更新速度很快，本文档也会尽量保持同步，文档号的命名与Spark版本一致，只是多了一位，最后一位表示文档的版本号。
由于技术水平、实验条件、经验等限制，当前只讨论Sparkcorestandalone版本中的核心功能，而不是全部功能。
诚邀各位小伙伴们加入进来，丰富和完善文档。
好久没有写这么完整的文档了，上次写还是三年前在学Ng的ML课程的时候，当年好有激情啊。
这次的撰写花了20+days，从暑假写到现在，大部分时间花在debug、画图和琢磨怎么写上，希望文档能对大家和自己都有所帮助。
内容本文档首先讨论job如何生成，然后讨论怎么执行，最后讨论系统相关的功能特性。
具体内容如下：Overview总体介绍Joblogicalplan介绍job的逻辑执行图（数据依赖图）Jobphysicalplan介绍job的物理执行图Shuffledetails介绍shuffle过程Architecture介绍系统模块如何协调完成整个job的执行CacheandCheckpoint介绍cache和checkpoint功能Broadcast介绍broadcast功能JobScheduling

在日常工作中，钉钉打卡成了我生活中不可或缺的一部分。然而，有时候这个看似简单的任务却给我带来了不少烦恼。 每天早晚，我总是得牢记打开钉钉应用，点击"工作台"，再找到"考勤打卡"进行签到。有时候因为工作忙碌，会忘记打卡，导致考勤异常，影响当月的工作评价。而且，由于我使用的是苹果手机，有时候系统更新后，钉钉的某些功能会出现异常，使得打卡变得更加麻烦。 另外，我的家人使用的是安卓手机，他们也经常抱怨钉钉打卡的繁琐。尤其是对于那些不太熟悉手机操作的长辈来说，每次打卡都是一次挑战。他们总是担心自己会操作失误，导致打卡失败。 为了解决这些烦恼，我开始思考是否可以通过编写一个全自动化脚本来实现钉钉打卡。经过一段时间的摸索和学习，我终于成功编写出了一个适用于苹果和安卓系统的钉钉打卡脚本。
