  8.         <value>file:/usr/local/hadoop/tmp</value>

  9.     </property>

  10. </configuration>

6.4.4、$vim hdfs-site.xml
將文件末尾修改為

  1. <configuration>

  2.     <property>

  3.         <name>dfs.replication</name>

  4.         <value>3</value>

  5.     </property>

6.4.5、$vim mapred-site.xml
將文件末尾 修改為

  1. <configuration>

  2.     <property>

  3.         <name>mapreduce.framework.name</name>

  4.         <value>yarn</value>

  5.     </property>

  6. </configuration>



6.4.6、$vim yarn-site.xml
將文件末尾修改為

  1. <configuration>

  2. <!-- Site specific YARN configuration properties -->

  3.     <property>

  4.         <name>yarn.nodemanager.aux-services</name>

  8.         <name>yarn.resourcemanager.hostname</name>

  9.         <value>hyw-spark-1</value>

  10.     </property>

  11. </configuration>

6.4.7、$vim slaves
添加如下內(nèi)容
hyw-spark-1
hyw-spark-2
hyw-spark-3
6.4.8、拷貝文件到slave節(jié)點(總共7個文件)
$scp hadoop-env.sh yarn-env.sh core-site.xml hdfs-site.xml mapred-site.xml yarn-site.xml slave hadoop@hyw-spark-2:/usr/local/spark/etc/spark/
$scp hadoop-env.sh yarn-env.sh core-site.xml hdfs-site.xml mapred-site.xml yarn-site.xml slave hadoop@hyw-spark-3:/usr/local/spark/etc/spark/

6.5、啟動hadoop集群
6.5.1、格式化NameNode
在Master節(jié)點上,執(zhí)行如下命令
$hdfs namenode -format
成功的話,會看到 “successfully formatted” 和 “Exitting with status 0” 的提示,若為 “Exitting with status 1” 則是出錯。
6.5.2、啟動HDFS(NameNode、DataNode)
在Master節(jié)點上,執(zhí)行如下命令
$start-dfs.sh
使用jps命令在Master上可以看到如下進程:
8757 SecondaryNameNode
7862 DataNode
7723 NameNode
8939 Jps
使用jps命令在兩個Slave上可以看到如下進程:
7556 Jps
7486 DataNode
6.5.3啟動Yarn(ResourceManager 、NodeManager)
在Master節(jié)點上,執(zhí)行如下命令
$start-yarn.sh
使用jps命令在Master上可以看到如下進程:
9410 Jps
8757 SecondaryNameNode
8997 ResourceManager
7862 DataNode
9112 NodeManager
7723 NameNode
使用jps命令在兩個Slave上可以看到如下進程:
7718 Jps
7607 NodeManager
7486 DataNode
6.5.4通過瀏覽器查看HDFS信息

七、spark安裝(在hadoop用戶下執(zhí)行)
7.1、下載文件到/opt目錄下,解壓文件到/usr/local
$cd /opt
$sudo tar -xzvf spark-2.2.1-bin-hadoop2.7.tgz  -C /usr/local
$cd /usr/local
$sudo mv spark-2.2.1-bin-hadoop2.7/ spark
$sudo chown -R hadoop:hadoop spark

7.2、設置環(huán)境變量
$sudo vi /etc/profile
添加如下內(nèi)容
export SPARK_HOME=/usr/local/spark
PATH=$JAVA_HOME/bin:$PATH:$HOME/bin:$HADOOP_HOME/bin:$HADOOP_HOME/sbin:$SCALA_HOME/bin:$SPARK_HOME/bin:$SPARK_HOME/sbin
更新環(huán)境變量
source /etc/profile

7.3、配置文件修改
以下操作均在master節(jié)點配置,配置完成后scp到slave節(jié)點
$cd /usr/local/spark/conf
7.3.1、$cp spark-env.sh.template spark-env.sh
$vim spark-env.sh
添加如下內(nèi)容
export JAVA_HOME=/opt/jdk1.8
export HADOOP_CONF_DIR=/usr/local/hadoop/etc/hadoop
export SCALA_HOME=/usr/local/scala
export SPARK_MASTER_IP=10.39.60.221
export SPARK_WORKER_MEMORY=1g
7.3.2、$cp slaves.template slaves
$vim slaves
添加如下內(nèi)容
hyw-spark-1
hyw-spark-2
hyw-spark-3
7.3.3拷貝文件到slave節(jié)點
$scp -r spark-env.sh slaves hadoop@hyw-spark-2:/usr/local/spark/conf/
$scp -r spark-env.sh slaves hadoop@hyw-spark-3:/usr/local/spark/conf/

7.4、啟動spark
7.4.1、啟動Master節(jié)點
Master節(jié)點上,執(zhí)行如下命令:
$start-master.sh
使用jps命令在master節(jié)點上可以看到如下進程:
10016 Jps
8757 SecondaryNameNode
8997 ResourceManager
7862 DataNode
9112 NodeManager
9832 Master
7723 NameNode
7.4.2、啟動worker節(jié)點
Master節(jié)點上,執(zhí)行如下命令:
$start-slaves.sh
使用jps命令在三個worker節(jié)點上可以看到如下進程:
7971 Worker
7486 DataNode
8030 Jps

7.5、通過瀏覽器查看spark信息
瀏覽器訪問http://10.39.60.221:8080,出現(xiàn)如下界面
