环境依赖:

当前环境:

• CentOS7.5

安装部署

整体安装过程

• 前置依赖 Java/SSH无密钥配置
• 环境变量配置
• 修改配置文件
• 创建格式化HDFS目录

安装在目录 /software/Spark/hadoop ,安装在其他目录，配置等对应修改

安装Java

Java一键安装脚本

# 全程 root 用户安装
install_path=/usr/java/
file_bash=/etc/profile
file_name=jdk-8u171-linux-x64.tar.gz

mkdir -p $install_path
tar -zxf $file_name -C $install_path

echo """
# jdk java
export JAVA_HOME=/usr/java/jdk1.8.0_171
export JRE_HOME=$JAVA_HOME/jre
export CLASSPATH=.:$JAVA_HOME/lib:$JRE_HOME/lib
export PATH=$JAVA_HOME/bin:$PATH
""" >> $file_bash
source $file_bash

安装包jdk-8u171-linux-x64.tar.gz下载

配置SSH无密钥登录

《参考SSH密钥配置文档》

Hadoop密钥配置较为特殊。如果Hadoop安装在非root用户。
例如。
sudo cat /home/scfan/.ssh/id_rsa.pub >> /home/scfan/.ssh/authorized_keys
sudo cat /root/.ssh/id_rsa.pub >> /home/scfan/.ssh/authorized_keys
sudo cat /home/scfan/.ssh/id_rsa.pub >> /root/.ssh/authorized_keys
sudo cat /root/.ssh/id_rsa.pub >> /root/.ssh/authorized_keys
需要将密钥加在自己用户和其他用户。
chmod 700 /home/scfan/.ssh/
chmod 600 /home/scfan/.ssh/authorized_keys
chmod 700 /root/.ssh/
chmod 600 /root/.ssh/authorized_keys

下载安装Hadoop

# 步骤1：下载hadoop
wget http://mirror.bit.edu.cn/apache/hadoop/common/hadoop-2.7.7/hadoop-2.7.7.tar.gz -P /software/Spark/spark_packages/.

# 步骤2：解压hadoop
tar -zxvf /software/Spark/spark_packages/hadoop-2.7.7.tar.gz  -C /software/Spark/.
mv /software/Spark/hadoop-2.7.7 /software/Spark/hadoop

# 步骤3：设置环境变量
sudo vim /etc/profile
增加如下几行
## hadoop home
export HADOOP_HOME=/software/Spark/hadoop  
# hadoop path
export PATH=$PATH:$HADOOP_HOME/bin
export PATH=$PATH:$HADOOP_HOME/sbin
# hadoop else env
export HADOOP_MAPRED_HOME=$HADOOP_HOME
export HADOOP_COMMON_HOME=$HADOOP_HOME
export HADOOP_HDFS_HOME=$HADOOP_HOME
export YARN_HOME=$HADOOP_HOME
export HADOOP_PREFIX=$HADOOP_HOME
export HADOOP_CONF_DIR=$HADOOP_HOME/etc/hadoop
# hadoop lib
export HADOOP_COMMON_LIB_NATIVE_DIR=$HADOOP_HOME/lib/native
export HADOOP_OPTS="-Djava.library.path=$HADOOP_HOME/lib"
export JAVA_LIBRARY_PATH=$HADOOP_HOME/lib/native:$JAVA_LIBRARY_PATH 

# 重新加载 /etc/profile
source /etc/profile

设置Hadoop配置文件

切换到配置文件目录
cd /software/Spark/hadoop/etc/hadoop

修改 hadoop_env.sh

修改原文件中
export JAVA_HOME=${JAVA_HOME}
为
export JAVA_HOME=/usr/java/jdk1.8.0_171

修改HDFS默认名称core-site.xml

<configuration>
    <property>
        <name>fs.default.name</name>
        <value>hdfs://192.168.172.70:9000</value>
    </property>
</configuration>

配置MapReduce yarn-site.xml

<configuration>
    <property>
        <name>yarn.nodemanager.aux-services</name>
        <value>mapreduce_shuffle</value>
    </property>
    <property>
        <name>yarn.nodemanager.aux-services.mapreduce.shuffle.class</name>
        <value>org.apache.hadoop.mapred.ShuffleHandler</value>
    </property>
    <property>
        <name>yarn.resourcemanager.address</name>
        <value>192.168.172.70:8032</value>
    </property>
    <property>
        <name>yarn.resourcemanager.scheduler.address</name>
        <value>192.168.172.70:8030</value>
    </property>
    <property>
        <name>yarn.resourcemanager.resource-tracker.address</name>
        <value>192.168.172.70:8031</value>
    </property>
    -->
</configuration>

配置Job mapred-site.xml

拷贝文件
cp mapred-site.xml.template mapred-site.xml

添加如下内容

<configuration>
    <property>
        <name>mapreduce.framework.name</name>
        <vaule>yarn</vaule>
    </property>
</configuration>

HDFS分布式文件系统 hdfs-site.xml

<configuration>
    <property>
        <name>dfs.replication</name>
        <vlaue>3</vlaue>
    </property>
    <property>
        <name>dfs.permissions</name>
        <value>false</value>
    </property>
    <property>
        <name>dfs.namenode.name.dir</name>
        <vlaue>file:/software/Spark/data/hadoop_data/hdfs/namenode</vlaue>
    </property>
    <property>
        <name>dfs.datanode.data.dir</name>
        <vlaue>file:/software/Spark/data/hadoop_data/hdfs/datanode</vlaue>
    </property>
</configuration>

创建并格式化HDFS目录

# 创建目录
mkdir -p /software/Spark/data/hadoop_data/hdfs/namenode
mkdir -p /software/Spark/data/hadoop_data/hdfs/datanode
# 格式化目录
# 进行格式化(如果报错，需要删除namenode下文件夹current)
hadoop namenode -format # 会删除HDFS数据

启动Hadoop

启动HDFS start-dfs.sh
启动Yarn start-yarn.sh
启动所有(含 dfs和yarn) start-all.sh

检查启动项

至少有如下启动项

[root@hbase hadoop]#  jps | grep -E 'ResourceManager|DataNode|NodeManager|SecondaryNameNode|NameNode'
26530 DataNode
26957 NodeManager
26862 ResourceManager
26429 NameNode
26717 SecondaryNameNode

问题
存在未启动情况，查看start-all.sh启动日志。或者在对应spark、hadoop日志目录下查看信息。

若存在datanode未启动（目录视情况而变动）(一般由于多次format导致的name和data的id不匹配)

(env) [scfan@WOM dfs]$ rm /tmp/hadoop-scfan/dfs/name/*
(env) [scfan@WOM dfs]$ rm /tmp/hadoop-scfan/dfs/data/*
(env) [scfan@WOM dfs]$ hadoop namenode -format
(env) [scfan@WOM dfs]$ stop-all.sh
(env) [scfan@WOM dfs]$ start-all.sh
