1、下载Spark安装包

官网网址：[http://spark.apache.org/downloads.html][http_spark.apache.org_downloads.html]

![70][]

# 2、Spark安装过程 #

## 2.1、上传并解压缩 ##

[potter@potter2 ~]$ tar -zxvf spark-2.3.0-bin-hadoop2.7.tgz -C apps/

## 2.2、修改配置文件 ##

##### （1）进入配置文件所在目录 #####

/home/potter/apps/spark-2.3.0-bin-hadoop2.7/conf

[potter @potter2 conf]$ ll 
       total 36 
       -rw-r–r-- 1 potter potter 996 Feb 23 03: 42 docker.properties.template 
       -rw-r–r-- 1 potter potter 1105 Feb 23 03: 42 fairscheduler.xml.template 
       -rw-r–r-- 1 potter potter 2025 Feb 23 03: 42 log4j.properties.template 
       -rw-r–r-- 1 potter potter 7801 Feb 23 03: 42 metrics.properties.template 
       -rw-r–r-- 1 potter potter 865 Feb 23 03: 42 slaves.template 
       -rw-r–r-- 1 potter potter 1292 Feb 23 03: 42 spark-defaults.conf.template 
       -rwxr-xr-x 1 potter potter 4221 Feb 23 03: 42 spark-env.sh.template

##### （2）修改spark-env.sh文件 #####

复制spark-env.sh.template，[并重命名为spark-env.sh][spark-env.sh]，并在文件最后添加配置内容

[potter @potter2 conf]$ cp spark-env.sh.template spark-env.sh 
       [potter @potter2 conf]$ vi spark-env.sh

export JAVA_HOME=/usr/local/java/jdk1.8.0_73 
       #export SCALA_HOME=/usr/share/scala 
       export HADOOP_HOME=/home/potter/apps/hadoop- 2.7.5 
       export HADOOP_CONF_DIR=/home/potter/apps/hadoop- 2.7.5/etc/hadoop 
       export SPARK_WORKER_MEMORY= 500m 
       export SPARK_WORKER_CORES= 1 
       export SPARK_DAEMON_JAVA_OPTS= "-Dspark.deploy.recoveryMode=ZOOKEEPER -Dspark.deploy.zookeeper.url=potter2:2181,potter3:2181,potter4:2181,potter5:2181 -Dspark.deploy.zookeeper.dir=/spark"

<table> 
 <tbody> 
  <tr> 
   <td>注：<br><p>#export SPARK_MASTER_IP=hadoop1&nbsp; 这个配置要注释掉。&nbsp;</p><p>集群搭建时配置的spark参数可能和现在的不一样，主要是考虑个人电脑配置问题，如果memory配置太大，机器运行很慢。&nbsp;</p><p>说明：&nbsp;</p><p>-Dspark.deploy.recoveryMode=ZOOKEEPER&nbsp; &nbsp; #说明整个集群状态是通过zookeeper来维护的，整个集群状态的恢复也是通过zookeeper来维护的。就是说用zookeeper做了spark的HA配置，Master(Active)挂掉的话，Master(standby)要想变成Master（Active）的话，Master(Standby)就要像zookeeper读取整个集群状态信息，然后进行恢复所有Worker和Driver的状态信息，和所有的Application状态信息；&nbsp;</p><p>-Dspark.deploy.zookeeper.url=potter2:2181,potter3:2181,potter4:2181,potter5:2181#将所有配置了zookeeper，并且在这台机器上有可能做master(Active)的机器都配置进来；（我用了4台，就配置了4台）&nbsp;</p><p>-Dspark.deploy.zookeeper.dir=/spark&nbsp;</p><p>这里的dir和zookeeper配置文件zoo.cfg中的dataDir的区别？？？&nbsp;</p><p>-Dspark.deploy.zookeeper.dir是保存spark的元数据，保存了spark的作业运行状态；&nbsp;</p>zookeeper会保存spark集群的所有的状态信息，包括所有的Workers信息，所有的Applactions信息，所有的Driver信息,如果集群</td> 
  </tr> 
 </tbody> 
</table>

##### （3）复制slaves.template变成slaves #####

[potter @potter2 conf]$ cp slaves.template slaves 
       [potter @potter2 conf]$ vi slaves

添加以下内容：

potter2 
       potter3 
       potter4 
       potter5

##### （4）将安装包分发给其他节点 #####

[potter @potter2 apps]$ scp -r spark- 2.3.0-bin-hadoop2.7/ potter3: P W D < / d i v > < / d i v > < / l i > < l i > < d i v c l a s s = " h l j s − l n − n u m b e r s " > < d i v c l a s s = " h l j s − l n − l i n e h l j s − l n − n " d a t a − l i n e − n u m b e r = " 2 " > < / d i v > < / d i v > < d i v c l a s s = " h l j s − l n − c o d e " > < d i v c l a s s = " h l j s − l n − l i n e " > [ p o t t e r < s p a n c l a s s = " h l j s − m e t a " > @ p o t t e r < / s p a n > 2 a p p s ] PWD</div></div></li><li><div class="hljs-ln-numbers"><div class="hljs-ln-line hljs-ln-n" data-line-number="2"></div></div><div class="hljs-ln-code"><div class="hljs-ln-line">[potter<span class="hljs-meta">@potter</span>2 apps] PWD</div></div></li><li><divclass="hljs−ln−numbers"><divclass="hljs−ln−linehljs−ln−n"data−line−number="2"></div></div><divclass="hljs−ln−code"><divclass="hljs−ln−line">[potter<spanclass="hljs−meta">@potter</span>2apps] scp -r spark- 2.3.0-bin-hadoop2.7/ potter4: P W D < / d i v > < / d i v > < / l i > < l i > < d i v c l a s s = " h l j s − l n − n u m b e r s " > < d i v c l a s s = " h l j s − l n − l i n e h l j s − l n − n " d a t a − l i n e − n u m b e r = " 3 " > < / d i v > < / d i v > < d i v c l a s s = " h l j s − l n − c o d e " > < d i v c l a s s = " h l j s − l n − l i n e " > [ p o t t e r < s p a n c l a s s = " h l j s − m e t a " > @ p o t t e r < / s p a n > 2 a p p s ] PWD</div></div></li><li><div class="hljs-ln-numbers"><div class="hljs-ln-line hljs-ln-n" data-line-number="3"></div></div><div class="hljs-ln-code"><div class="hljs-ln-line">[potter<span class="hljs-meta">@potter</span>2 apps] PWD</div></div></li><li><divclass="hljs−ln−numbers"><divclass="hljs−ln−linehljs−ln−n"data−line−number="3"></div></div><divclass="hljs−ln−code"><divclass="hljs−ln−line">[potter<spanclass="hljs−meta">@potter</span>2apps] scp -r spark- 2.3.0-bin-hadoop2.7/ potter5: P W D < / d i v > < / d i v > < / l i > < / o l > < / c o d e > < d i v c l a s s = " h l j s − b u t t o n 2 " d a t a − t i t l e = " 复 制 " > < / d i v > < / p r e > < h 2 > < a n a m e = " t 4 " > < / a > 2.3 、 配 置 环 境 变 量 < / h 2 > < p r e o n c l i c k = " h l j s . c o p y C o d e ( e v e n t ) " > < c o d e c l a s s = " l a n g u a g e − j a v a h l j s " > [ p o t t e r < s p a n c l a s s = " h l j s − m e t a " > @ p o t t e r < / s p a n > 2   ] PWD</div></div></li></ol></code><div class="hljs-button {2}" data-title="复制"></div></pre><h2><a name="t4"></a>2.3、配置环境变量</h2><pre "hljs.copyCode(event)"><code class="language-java hljs">[potter<span class="hljs-meta">@potter</span>2 ~] PWD</div></div></li></ol></code><divclass="hljs−button2"data−title="复制"></div></pre><h2><aname="t4"></a>2.3、配置环境变量</h2><preonclick="hljs.copyCode(event)"><codeclass="language−javahljs">[potter<spanclass="hljs−meta">@potter</span>2 ] vi .bashrc

export SPARK_HOME=/home/potter/apps/spark- 2.3.0-bin-hadoop2.7 
       export PATH= P A T H : PATH: PATH:SPARK_HOME/bin

保存并使其立即生效

[potter@potter2 ~]$ source .bashrc

# 2.4、配置spark-defaults.conf #

Spark默认是本地模式：

![70 1][]

进入/home/potter/apps/spark-2.3.0-bin-hadoop2.7/conf

复制一个spark-defaults.conf文件

[potter@potter2 conf]$ cp spark-defaults.conf.template spark-defaults.conf

[potter@potter2 conf]$ vi spark-defaults.conf

# This is useful for setting default environmental settings. 
        
        # Example: 
        spark.master spark: //potter2:7077,potter3:7077,potter4:7077,potter5:7077 
        # spark.eventLog.enabled true 
        # spark.eventLog.dir hdfs: //namenode:8021/directory 
        # spark.serializer org.apache.spark.serializer.KryoSerializer 
        # spark.driver.memory 5g

## 3.2、启动HDFS集群 ##

任意一个节点执行即可

[potter@potter2 ~]$ start-dfs.sh

## 3.3、再启动Spark集群 ##

[potter @potter2 ~]$ cd apps/spark- 2.3.0-bin-hadoop2.7/sbin/ 
       [potter @potter2 sbin]$ ./start-all.sh

## 3.4、查看进程 ##

[potter @potter2 sbin]$ jps

       3945 Jps 
       3916 Worker

## 3.5、启动spark ##

出现以下就算启动成功：

![70 3][]

## 3.5、问题 ##

查看进程发现spark集群只有hadoop1成功启动了Master进程，其他3个节点均没有启动成功，需要手动启动，进入到/home/hadoop/apps/spark/sbin目录下执行以下命令，3个节点都要执行

[potter @potter3 ~]$ cd apps/spark- 2.3.0-bin-hadoop2.7/sbin/ 
       [potter @potter3 sbin]$ ./start-master.sh

[potter @potter4 ~]$ cd apps/spark- 2.3.0-bin-hadoop2.7/sbin/ 
       [potter @potter4 sbin]$ ./start-master.sh

[potter @potter5 ~]$ cd apps/spark- 2.3.0-bin-hadoop2.7/sbin/ 
       [potter @potter5 sbin]$ ./start-master.sh

## 3.6、执行之后再次查看进程 ##

Master进程和Worker进程都可以启动成功

[potter @potter3 sbin]$ jps 
       3441 DataNode 
       3284 QuorumPeerMain 
       4581 Worker 
       3576 JournalNode 
       3372 NameNode 
       3676 DFSZKFailoverController 
       5020 Jps 
       4894 Master

       3456 JournalNode 
       4179 Master 
       3356 DataNode 
       3260 QuorumPeerMain 
       4238 Jps

       3304 DataNode 
       4057 Jps 
       3916 Worker 
       3998 Master

# 4、验证 #

## 4.1、查看Web界面Master状态 ##

potter2是ALIVE状态，potter3、potter4和potter5均是STANDBY状态

**potter2**

![70 4][]

**potter3**

![70 5][]

**potter4**

![70 6][]

**potter5**

![70 7][]

## 4.2、手动干掉potter2上面的Master进程，观察是否进行自动切换 ##

[potter @potter2 ~]$ jps 
       6464 Master 
       6528 Worker 
       6901 Jps 
       3909 NameNode 
       3703 QuorumPeerMain 
       4412 DFSZKFailoverController 
       4204 JournalNode 
       4014 DataNode 
       [potter @potter2 ~]$ kill - 9 6464 
       [potter @potter2 ~]$

干掉potter2上的Master进程之后，再次查看web界面

**potter2**节点，由于Master进程被干掉，所以界面无法访问

![70 8][]

**potter3**节点，Master被干掉之后，potter3节点上的Master成功篡位成功，成为ALIVE状态

![70 9][]

**potter4**

**![70 6][]**

**potter5**

# 五、执行Spark程序on standalone #

##### （1）执行第一个Spark程序 #####

[potter @potter2 apps]$ cd 
       [potter @potter2 ~]$ /home/potter/apps/spark- 2.3.0-bin-hadoop2.7/bin/spark-submit </div> 
       > – class org.apache.spark.examples.SparkPi </span> 
       > –master spark?/potter2:7077 </span> 
       > –executor-memory 500m </span> 
       > –total-executor-cores 1 </span> 
       > /home/potter/apps/spark-2.3.0-bin-hadoop2.7/examples/jars/spark-examples_2.11-2.3.0.jar </span> 
       > 100

其中的spark://hadoop1:7077是下图中的地址

![70 10][]

运行结果：

![70 11][]

（2）启动spark-shell

/home/potter/apps/spark- 2.3.0-bin-hadoop2.7/bin/spark-shell </div> 
       –master spark: //potter2:7077 </span> 
       –executor-memory 500m </div> 
       –total-executor-cores 1

参数说明：

<table> 
 <tbody> 
  <tr> 
   <td>–master spark://potter2:7077 指定Master的地址<br>–executor-memory 500m:指定每个worker可用内存为500m<br>–total-executor-cores 1: 指定整个集群使用的cup核数为1个</td> 
  </tr> 
 </tbody> 
</table>

![70 12][]

注意：

如果启动spark shell时没有指定master地址，但是也可以正常启动spark shell和执行spark shell中的程序，其实是启动了spark的local模式，该模式仅在本机启动一个进程，没有与集群建立联系。

Spark Shell中已经默认将SparkContext类初始化为对象sc。用户代码如果需要用到，则直接应用sc即可

Spark Shell中已经默认将SparkSQl类初始化为对象spark。用户代码如果需要用到，则直接应用spark即可

##### （3）在spark shell中编写workcount程序 #####

###### 1）编写一个workcount.txt文件并上传到HDFS上的 / 目录下 ######

[potter @potter2 ~]$ vi workcount.txt 
       [potter @potter2 ~]$ hadoop fs -put hello.txt /

workcount.txt的内容是：

you，jump 
       i,jump

###### 2）在spark shell中用scala语言编写spark程序 ######

scala> sc.textFile(”/workcount.txt").flatMap(.split(",")).map((,1)).reduceByKey(+).collect

说明：

<table> 
 <tbody> 
  <tr> 
   <td>sc是SparkContext对象，该对象是提交spark程序的入口<br>textFile("/spark/hello.txt")是hdfs中读取数据<br>flatMap(<em>.split(" "))先map再压平<br>map((</em>,1))将单词和1构成元组<br>reduceByKey(<em>+</em>)按照key进行reduce，并将value累加<br>saveAsTextFile("/spark/out")将结果写入到hdfs中</td> 
  </tr> 
 </tbody> 
</table>

运行结果：

![70 13][]

# 六、执行Spark程序on YARN #

##### （1）前提 #####

成功启动zookeeper集群、HDFS集群、YARN集群

##### （2）启动Spark on YARN #####

[potter@potter2 ~]$ spark-shell --master yarn --deploy-mode client

报错如下：

![70 14][]

报错原因：内存资源给的过小，yarn直接kill掉进程，则报rpc连接失败、ClosedChannelException等错误。

解决方法：

先停止YARN服务，然后修改yarn-site.xml，增加如下内容

<property> 
       <name>yarn.nodemanager.vmem-check-enabled</name> 
       <value> false</value> 
       <description>Whether virtual memory limits will be enforced for containers</description> 
       </property> 
       <property> 
       <name>yarn.nodemanager.vmem-pmem-ratio</name> 
       <value> 4</value> 
       <description>Ratio between virtual memory to physical memory when setting memory limits for containers</description> 
       </property>

将新的yarn-site.xml文件分发到其他Hadoop节点对应的目录下，最后在重新启动YARN。

重新执行以下命令启动spark on yarn

[potter@potter2 hadoop]$ spark-shell --master yarn --deploy-mode client

![70 15][]

##### （3）打开YARN的web界面 #####

打开YARN的web界面：http：//potter4:8088

可以看到Spark shell应用程序正在运行

![70 16][]

单击ID号链接，可以看到该应用程序的详细信息

![70 17][]

单击“ApplicationMaster”链接

![70 18][]

##### （4）运行程序 #####

scala> val array = Array( 1, 2, 3, 4, 5) 
       array: Array[Int] = Array( 1, 2, 3, 4, 5) 
       
       scala> val rdd = sc.makeRDD(array)
