benchmark的意思是基准，或者说是基准数据集。一、Benchmark简介Benchmark是一个评价方式，在整个计算机领域有着长期的应用。Benchmark在计算机领域应用最成功的就是性能测试，主要测试负载的执行时间、传输速度、吞吐量、资源占用率等。二、Benchmark的组成Benchmark的核心由3部分组成：数据集、 工作负载、度量指标。1、数据集数据类型分为结构化数据、半结构化数据和非结构化数据。由于大数据环境下的数据类型复杂，负载多样，所以大数据Benchmark需要生成3种类型的数据和对应负载。2、工作负载互联网领域数据庞大，用户量大，成为大数据问题产生的天然土壤。对工作负载理解和设计可以从以下几个维度来看：密集计算类型；计算范式；计算延迟和应用领域。3、度量指标性能高估的两大利器就是Benchmark和Profile工具。Benchmark用压力测试挖掘整个系统的性能状况，而Profile工具最大限度地呈现系统的运行时状态和性能指标，方便用户诊断性能问题和进行调优。

创建 maven 工程使用下面命令创建一个普通的 maven 工程：bash$ mvn archetype:generate -DgroupId=com.cloudera.sparkwordcount -DartifactId=sparkwordcount -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false将 sparkwordcount 目录重命名为simplesparkapp，然后，在 simplesparkapp 目录下添加 scala 源文件目录：bash$ mkdir -p sparkwordcount/src/main/scala/com/cloudera/sparkwordcount修改 pom.xml 添加 scala 和 spark 依赖：xml <dependencies> <dependency> <groupId>org.scala-lang</groupId> <artifactId>scala-library</artifactId> <version>2.10.4</version> </dependency> <dependency> <groupId>org.apache.spark</groupId> <artifactId>spark-core_2.10</artifactId> <version>1.2.0-cdh5.3.0</version> </dependency> </dependencies>添加编译 scala 的插件：xml <plugin> <groupId>org.scala-tools</groupId> <artifactId>maven-scala-plugin</artifactId> <executions> <execution> <goals> <goal>compile</goal> <goal>testCompile</goal> </goals> </execution> </executions></plugin>添加 scala 编译插件需要的仓库：xml<pluginRepositories> <pluginRepository> <id>scala-tools.org</id> <name>Scala-tools Maven2 Repository</name> <url>http://scala-tools.org/repo-releases</url> </pluginRepository></pluginRepositories>另外，添加 cdh hadoop 的仓库：xml <repositories> <repository> <id>scala-tools.org</id> <name>Scala-tools Maven2 Repository</name> <url>http://scala-tools.org/repo-releases</url> </repository> <repository> <id>maven-hadoop</id> <name>Hadoop Releases</name> <url>https://repository.cloudera.com/content/repositories/releases/</url> </repository> <repository> <id>cloudera-repos</id> <name>Cloudera Repos</name> <url>https://repository.cloudera.com/artifactory/cloudera-repos/</url> </repository> </repositories>最后，完整的 pom.xml 文件见： https://github.com/javachen/simplesparkapp/blob/master/pom.xml 。运行下面命令检查工程是否能够成功编译：bashmvn package编写示例代码以 WordCount 为例，该程序需要完成以下逻辑：读一个输入文件统计每个单词出现次数过滤少于一定次数的单词对剩下的单词统计每个字母出现次数在 MapReduce 中，上面的逻辑需要两个 MapReduce 任务，而在 Spark 中，只需要一个简单的任务，并且代码量会少 90%。编写 Scala 程序 如下：scalaimport org.apache.spark.SparkContextimport org.apache.spark.SparkContext._import org.apache.spark.SparkConfobject SparkWordCount { def main(args: Array[String]) { val sc = new SparkContext(new SparkConf().setAppName("Spark Count")) val threshold = args(1).toInt // split each document into words val tokenized = sc.textFile(args(0)).flatMap(_.split(" ")) // count the occurrence of each word val wordCounts = tokenized.map((_, 1)).reduceByKey(_ + _) // filter out words with less than threshold occurrences val filtered = wordCounts.filter(_._2 >= threshold) // count characters val charCounts = filtered.flatMap(_._1.toCharArray).map((_, 1)).reduceByKey(_ + _) System.out.println(charCounts.collect().mkString(", ")) charCounts.saveAsTextFile("world-count-result") }}Spark 使用懒执行的策略，意味着只有当 动作 执行的时候， 转换 才会运行。上面例子中的 动作 操作是 collect 和 saveAsTextFile ，前者是将数据推送给客户端，后者是将数据保存到 HDFS。作为对比， Java 版的程序 如下：javaimport java.util.ArrayList;import java.util.Arrays;import org.apache.spark.api.java.*;import org.apache.spark.api.java.function.*;import org.apache.spark.SparkConf;import scala.Tuple2;public class JavaWordCount { public static void main(String[] args) { JavaSparkContext sc = new JavaSparkContext(new SparkConf().setAppName("Spark Count")); final int threshold = Integer.parseInt(args[1]); // split each document into words JavaRDD tokenized = sc.textFile(args[0]).flatMap( new FlatMapFunction() { public Iterable call(String s) { return Arrays.asList(s.split(" ")); } } ); // count the occurrence of each word JavaPairRDD counts = tokenized.mapToPair( new PairFunction() { public Tuple2 call(String s) { return new Tuple2(s, 1); } } ).reduceByKey( new Function2() { public Integer call(Integer i1, Integer i2) { return i1 + i2; } } );另外， Python 版的程序 如下：pythonimport sysfrom pyspark import SparkContextfile="inputfile.txt"count=2if __name__ == "__main__": sc = SparkContext(appName="PythonWordCount") lines = sc.textFile(file, 1) counts = lines.flatMap(lambda x: x.split(" ")) .map(lambda x: (x, 1)) .reduceByKey(lambda a, b: a + b) .filter(lambda (a, b) : b >= count) .flatMap(lambda (a, b): list(a)) .map(lambda x: (x, 1)) .reduceByKey(lambda a, b: a + b) print ",".join(str(t) for t in counts.collect()) sc.stop()编译运行下面命令生成 jar：bash$ mvn package运行成功之后，会在 target 目录生成 sparkwordcount-0.0.1-SNAPSHOT.jar 文件。运行因为项目依赖的 spark 版本是 1.2.0-cdh5.3.0 ，所以下面的命令只能在 CDH 5.3 集群上运行。首先，将测试文件 inputfile.txt 上传到 HDFS 上；bash$ wget https://github.com/javachen/simplesparkapp/blob/master/data/inputfile.txt$ hadoop fs -put inputfile.txt其次，将 sparkwordcount-0.0.1-SNAPSHOT.jar 上传到集群中的一个节点；然后，使用 spark-submit 脚本运行 Scala 版的程序：bash$ spark-submit --class com.cloudera.sparkwordcount.SparkWordCount --master local sparkwordcount-0.0.1-SNAPSHOT.jar inputfile.txt 2或者，运行 Java 版本的程序：bash$ spark-submit --class com.cloudera.sparkwordcount.JavaWordCount --master local sparkwordcount-0.0.1-SNAPSHOT.jar inputfile.txt 2对于 Python 版的程序，运行脚本为：bash$ spark-submit --master local PythonWordCount.py如果，你的集群部署的是 standalone 模式，则你可以替换 master 参数的值为 spark://<master host>:<master port> ，也可以以 Yarn 的模式运行。

me列求最大值，首先通过mapToPair对数据按照月份进行分类。已经确保这些数据是在相同的月份的。然后通过reduceByKey进行计算后结果出来最大值是41821.02778。而不是41821.04167。

I would like to work in a big city as there are more/better chances of earning cold hard cash in the city area since the expansion and advancement of globalisation. Furthermore, it would be better if I get a job in the city area as there are many incentives for someone that is working in the city, one good example is the convinience of transport that any city must have. The various forms of transport in the city is one thing that not all small towns may provide to its people, hence this is one good reason why I would like to work in a big city as compared to a small town. Another reason why I would like to work in a big city is because I grew up in a city, I understand the structure of the society in a city area, and since this is extremely beneficial to my work life, then why not take advantage of this point and put it into good use?现场打出来的，以后需要文章碰巧我在线就能帮你解决，顺便练练水平~~

Dylan Marlais Thomas (October 27, 1914 – November 9, 1953) was a Welsh poet and writer.Dylan Thomas was born in the coastal city of Swansea, Wales. His father David, who was a writer and possessed a degree in English, brought his son up to speak English rather than Thomas"s mother"s, Florence Hannah Thomas, native language, Welsh. He had one sister, Nancy, who was nine years older than him. His middle name, "Marlais", came from the bardic name of his uncle, the Unitarian minister Gwilym Marles (whose real name was William Thomas). Thomas was unable to actively fight in World War II because he was considered too frail, however he still served the war effort by writing scripts for government propaganda.He attended the boys-only Swansea Grammar School, in the Mount Pleasant district of the city, where his father taught English Literature. It was in the school"s magazine that Thomas saw his first poem published. He left school at age 16 to become a reporter for a year and a half.Thomas"s childhood was spent largely in Swansea, with regular summer trips to visit his mother"s family on their Carmarthen farm. These rural sojourns, and their contrast with the town life of Swansea, provided substance for much of his work, notably many short stories and radio essays and the poem Fern Hill.Thomas wrote half his poems and many short stories when he lived at the family home at 5 Cwmdonkin Drive; And death shall have no dominion is one of the best known works written at this address. His highly acclaimed[1] first poetry volume, 18 Poems, was published in November 1934. The publication of Deaths and Entrances in 1946 was a major turning point[2][3][4] in his career, with widespread recognition that a great poet had indeed emerged. Thomas "became a very successful orator...was extremely well-known during his life for being a versatile and dynamic speaker and he was best known for his poetry readings."[5] His immensely striking and powerful voice would captivate American audiences during his speaking tours of the early 1950s. He made over two hundred broadcasts for the BBC.Dylan Thomas met his wife Caitlin and "the love affair started in a Fitzrovia pub in the spring of 1936. A young Irish dancer called Caitlin Macnamara sat on a stool at the bar: blonde, blue-eyed and drinking gin. To the drunken Welsh poet who staggered towards her through the smokey fug of The Wheatsheaf, she appeared an angelic beauty. And when finally the poet reached her, eccentrically laying his head in her lap, he mumbled a proposal of marriage. This unorthodox first encounter between Dylan Thomas and his wife is a central part of the Bohemian mythology that surrounds the memory of one of Britain"s best loved creative talents."[6]In 1937, Thomas married MacNamara and would have three children with her, although the marriage was tempestuous. There were affairs and rumours of affairs on both sides; Caitlin had an affair with Augustus John before, and quite possibly after, she married Thomas. In January of 1939 came the birth of their first child, a boy whom they named Llewelyn (died in 2000). He was followed in March of 1943 by a daughter, Aeronwy. A second son and third child, Colum Garan, was born in July 1949.Thomas liked to boast about his drinking. He was known to comment, "An alcoholic is someone you don"t like who drinks as much as you do."[7] During an incident on November 3, 1953, Thomas returned to the Chelsea Hotel in New York and exclaimed "I"ve had 18 straight whiskies; I think this is a record."He collapsed on November 9, 1953 at the White Horse Tavern, in Greenwich Village, Manhattan after drinking heavily while on a promotional speaking tour; Thomas later died at St. Vincent"s Hospital. The primary cause of his death is recorded as pneumonia, with pressure on the brain and a fatty liver given as contributing factors. His last words, according to Jack Heliker, were: "After 39 years, this is all I"ve done." Following his death, his body was brought back to Wales for burial in the village churchyard at Laugharne. His wife, Caitlin, died in 1994, and was buried alongside him. It is said that Mr. Thomas"s favorite drink was the Whiskey Sour, which, on several occasions, he referred to as "jolly good nosh, this."As would be expected of a famous poet whose best known line is "Do not go gentle into that good night", many memorials have been constructed or converted to honour Thomas. Tourists in his home town of Swansea can visit a statue in the maritime quarter, the Dylan Thomas Theatre, and the Dylan Thomas Centre, formerly the town"s guildhall. The latter is now a literature centre, where exhibitions and lectures are held and is the setting for the city"s annual Dylan Thomas Festival. Another monument to Thomas stands in Cwmdonkin Park, one of his favourite childhood haunts, close to his birthplace at 5 Cwmdonkin Drive. The memorial is inscribed with the closing lines from one of his best-loved poems, Fern Hill: "Oh as I was young and easy in the mercy of his means/Time held me green and dying/Though I sang in my chains like the sea."[11] This is inscribed on a rock in a closed-off garden within the park. Thomas"s home in Laugharne, the Boat House, is also a memorial. The Powerful Coolmore Stud have a Colt (horse) called Dylan Thomas which won the Irish Derby on the 2nd July 2006.Several of the pubs in Swansea also have associations with the poet. One of Swansea"s oldest pubs, the No Sign Bar, was a regular haunt, renamed the Wine Vaults in his story The Followers.In 2004 a new literary prize, the Dylan Thomas Prize,[12] was created in honour of the poet. It is awarded to the best published writer in English under the age of 30.His obituary was written by his long term friend Vernon Watkins.A class 153 locomotive was named Dylan Thomas 1914 - 1953.Igor Stravinsky wrote In memoriam Dylan Thomas: Dirge canons and song (1954) for tenor voice, string quartet, and four trombones, based on "Do not go gentle".A song by a Welsh rock band, The Rambones, pays tribute to Thomas in the final line, as they sing, "I choose to go gentle, but I promise/It"s with no offense to Dylan Thomas".The cover of the Beatles album Sgt. Pepper"s Lonely Hearts Club Band contains a photograph of Dylan Thomas.Alternative rock band The Slip make a reference to the poet in their 2006 song, "Airplane/Primitive" from the album Eisenhower: "It is the day before the rest of my life / And I feel like Dylan Thomas".Musician Ben Taylor named his 2003 album "famous among the barns" as tribute to Dylan Thomas.In the Simon & Garfunkel song "A Simple Desultory Philippic" they sing ironically: "He doesn"t dig poetry. He"s so unhip that / When you say Dylan, he thinks you"re talking about Dylan Thomas, / Whoever he was".

额，只有英文歌词诶~These frantic memories They bring me down, tormenting peace The darkness drowns me I"m restless without sleep When day breaks, I"m still awake, I recall my mistakes I"ll be never alone, never again, never alone, I"ll be never alone, never again, never alone...

I"ll make my way through the darkest hours of my days! Those frozen memories Laid out for me, all I can see The night surrounds me Destroying harmony What lies beneath, demising me? I"ve lost my purity I"ll be never alone, never again, never alone, I"ll be never alone, never again, never alone... When all my hope is gone, I"m waiting for the dawn I raise my head and find my own way out of the dark I"ve left my past behind I"m reaching for the light I"m not afraid to live my life - I"ll take what is mine. I"ll make my way through the darkest hours of my days!

开始界面wireshark是捕获机器上的某一块网卡的网络包，当你的机器上有多块网卡的时候，你需要选择一个网卡。点击Caputre->Interfaces.. 出现下面对话框，选择正确的网卡。然后点击"Start"按钮, 开始抓包Wireshark 窗口介绍WireShark 主要分为这几个界面1. Display Filter(显示过滤器)， 用于过滤2. Packet List Pane(封包列表)， 显示捕获到的封包， 有源地址和目标地址，端口号。 颜色不同，代表3. Packet Details Pane(封包详细信息), 显示封包中的字段4. Dissector Pane(16进制数据)5. Miscellanous(地址栏，杂项)Wireshark 显示过滤使用过滤是非常重要的， 初学者使用wireshark时，将会得到大量的冗余信息，在几千甚至几万条记录中，以至于很难找到自己需要的部分。搞得晕头转向。过滤器会帮助我们在大量的数据中迅速找到我们需要的信息。过滤器有两种，一种是显示过滤器，就是主界面上那个，用来在捕获的记录中找到所需要的记录一种是捕获过滤器，用来过滤捕获的封包，以免捕获太多的记录。 在Capture -> Capture Filters 中设置保存过滤在Filter栏上，填好Filter的表达式后，点击Save按钮， 取个名字。比如"Filter 102",Filter栏上就多了个"Filter 102" 的按钮。过滤表达式的规则表达式规则 1. 协议过滤比如TCP，只显示TCP协议。2. IP 过滤比如 ip.src ==192.168.1.102 显示源地址为192.168.1.102，ip.dst==192.168.1.102, 目标地址为192.168.1.1023. 端口过滤tcp.port ==80, 端口为80的tcp.srcport == 80, 只显示TCP协议的愿端口为80的。4. Http模式过滤http.request.method=="GET", 只显示HTTP GET方法的。5. 逻辑运算符为 AND/ OR常用的过滤表达式过滤表达式 用途http 只查看HTTP协议的记录ip.src ==192.168.1.102 or ip.dst==192.168.1.102 源地址或者目标地址是192.168.1.102封包列表(Packet List Pane)封包列表的面板中显示，编号，时间戳，源地址，目标地址，协议，长度，以及封包信息。 你可以看到不同的协议用了不同的颜色显示。你也可以修改这些显示颜色的规则， View ->Coloring Rules.封包详细信息 (Packet Details Pane)这个面板是我们最重要的，用来查看协议中的每一个字段。各行信息分别为Frame: 物理层的数据帧概况Ethernet II: 数据链路层以太网帧头部信息Internet Protocol Version 4: 互联网层IP包头部信息Transmission Control Protocol: 传输层T的数据段头部信息，此处是TCPHypertext Transfer Protocol: 应用层的信息，此处是HTTP协议wireshark与对应的OSI七层模型TCP包的具体内容 从下图可以看到wireshark捕获到的TCP包中的每个字段。实例分析TCP三次握手过程看到这， 基本上对wireshak有了初步了解， 现在我们看一个TCP三次握手的实例三次握手过程为这图我都看过很多遍了， 这次我们用wireshark实际分析下三次握手的过程。打开wireshark, 打开浏览器输入 http://www.cnblogs.com/tankxiao在wireshark中输入http过滤， 然后选中GET /tankxiao HTTP/1.1的那条记录，右键然后点击"Follow TCP Stream",这样做的目的是为了得到与浏览器打开网站相关的数据包，将得到如下图图中可以看到wireshark截获到了三次握手的三个数据包。第四个包才是HTTP的， 这说明HTTP的确是使用TCP建立连接的。第一次握手数据包客户端发送一个TCP，标志位为SYN，序列号为0， 代表客户端请求建立连接。 如下图第二次握手的数据包服务器发回确认包, 标志位为 SYN,ACK. 将确认序号(Acknowledgement Number)设置为客户的I S N加1以.即0+1=1, 如下图第三次握手的数据包客户端再次发送确认包(ACK) SYN标志位为0,ACK标志位为1.并且把服务器发来ACK的序号字段+1,放在确定字段中发送给对方.并且在数据段放写ISN的+1, 如下图:就这样通过了TCP三次握手，建立了连接
