# 1.概述 #

Spark客户端直接连接Yarn，不需要额外构建Spark集群。有yarn-client和yarn-cluster两种模式，主要区别在于：Driver程序的运行节点。

*  yarn-client：Driver程序运行在客户端，适用于交互、调试，希望立即看到app的输出
 *  yarn-cluster：Driver程序运行在由RM（ResourceManager）启动的AP（APPMaster）适用于生产环境。

## 二、集群配置 ##

### 2.1 spark-env.sh ###

[xiaokang@hadoop01 conf]$ cp spark-env.sh.template spark-env.sh
    
    export JAVA_HOME=/opt/moudle/jdk1.8.0_191
    export SCALA_HOME=/opt/moudle/scala-2.11.12
    YARN_CONF_DIR=/opt/software/hadoop-2.7.7/etc/hadoop
    export SPARK_DAEMON_JAVA_OPTS="-Dspark.deploy.recoveryMode=ZOOKEEPER -Dspark.deploy.zookeeper.url=hadoop01:2181,hadoop02:2181,hadoop03:2181 -Dspark.deploy.zookeeper.dir=/ha-spark"
    export SPARK_HISTORY_OPTS="-Dspark.history.ui.port=18080 -Dspark.history.retainedApplications=24 -Dspark.history.fs.logDirectory=hdfs://hadoop01:9000/spark-jobhistory"

### 2.2 spark-defaults.conf ###

[xiaokang@hadoop01 conf]$ cp spark-defaults.conf.template spark-defaults.conf

    spark.master                     spark://hadoop01:7077,hadoop02:7077
    spark.eventLog.enabled           true
    spark.eventLog.dir               hdfs://hadoop01:9000/spark-jobhistory
    spark.yarn.historyServer.address               hadoop01:18080

### 2.3 slaves ###

[xiaokang@hadoop01 conf]$ cp slaves.template slaves
    
    hadoop01
    hadoop02
    hadoop03

### 2.4 yarn-site.xml ###

<property>
        <name>yarn.nodemanager.pmem-check-enabled</name>
        <value>false</value>
    </property>
    
    <property>
        <name>yarn.nodemanager.vmem-check-enabled</name>
        <value>false</value>
    </property>
    
    <property>
        <name>yarn.log.server.url</name>
        <value>http://hadoop01:19888/jobhistory/logs</value>
    </property>

### 2.5 分发 ###

[xiaokang@hadoop01 ~]$ distribution.sh /opt/software/spark-2.4.5
    [xiaokang@hadoop01 ~]$ distribution.sh /opt/software/hadoop-2.7.7/etc/hadoop/yarn-site.xml

## 三、启动集群 ##

### 3.1 启动ha-hadoop集群 ###

[xiaokang@hadoop01 ~]$ ha-hadoop.sh start

### 3.2 在hadoop01上启动spark集群 ###

# 进入/opt/software/spark-2.4.5/sbin目录并启动集群
    [xiaokang@hadoop01 sbin]$ ./start-all.sh

### 3.3 在hadoop02上启动备Master ###

# 进入/opt/software/spark-2.4.5/sbin目录并启动备Master
    [xiaokang@hadoop02 sbin]$ ./start-master.sh

### 3.4 在hadoop01上启动任务历史服务器 ###

# 进入/opt/software/spark-2.4.5/sbin目录并启动任务历史服务器
    [xiaokang@hadoop01 sbin]$ ./start-history-server.sh

## 四、查看集群 ##

### 4.1 jps进程查看 ###

[xiaokang@hadoop01 ~]$ call-cluster.sh jps
    --------hadoop01--------
    10881 NodeManager
    11265 HistoryServer
    13058 Master
    10131 NameNode
    10470 JournalNode
    11176 Worker
    10250 DataNode
    10683 DFSZKFailoverController
    10796 JobHistoryServer
    12973 Jps
    9935 QuorumPeerMain
    --------hadoop02--------
    7232 QuorumPeerMain
    7648 DFSZKFailoverController
    7505 JournalNode
    7831 NodeManager
    8183 Worker
    7321 NameNode
    7402 DataNode
    9099 Jps
    7743 ResourceManager
    8255 Master
    --------hadoop03--------
    7313 DataNode
    8273 Jps
    7234 QuorumPeerMain
    7843 Worker
    7545 ResourceManager
    7419 JournalNode
    7663 NodeManager

### 4.2 Web UI查看 ###

[xiaokang@hadoop01 sbin]$ cat /opt/software/spark-2.4.5/logs/spark-xiaokang-org.apache.spark.deploy.master.Master-1-hadoop01.out | grep MasterWebUI
    
    20/05/31 08:32:08 INFO MasterWebUI: Bound MasterWebUI to 0.0.0.0, and started at http://hadoop01:8081

通过启动日志可以看到hadoop01的`MasterWebUI`的端口号为8081

![图片][acb0dee03481dc624e88931b646bc82e.png]

[xiaokang@hadoop02 sbin]$ cat /opt/software/spark-2.4.5/logs/spark-xiaokang-org.apache.spark.deploy.master.Master-1-hadoop02.out | grep MasterWebUI
    
    20/05/31 08:32:43 INFO MasterWebUI: Bound MasterWebUI to 0.0.0.0, and started at http://hadoop02:8082

通过启动日志可以看到hadoop02的`MasterWebUI`的端口号为8082

![图片][99fafadbcf722ebfb9263aa24c8cb6d1.png]

hadoop01上的任务历史服务器端口号为18080

## 五、计算 PI (测试高可用) ##

[xiaokang@hadoop01 ~]$ spark-submit --master yarn --class org.apache.spark.examples.SparkPi /opt/software/spark-2.4.5/examples/jars/spark-examples_2.11-2.4.5.jar 1000

运行过程中将主Master给kill掉，测试是否高可用

[xiaokang@hadoop01 ~]$ kill -9 11091

杀掉主Master之后，程序还是同样在执行，可以看到hadoop02的`MasterWebUI`中状态显示为recovering

最终计算结果如下：

通过hadoop03上YARN的`8088`可以查看历史任务
