一、安装hadoop、HA及配置journalnode

实现namenode HA

实现resourcemanager HA

namenode节点之间通过journalnode同步元数据

首先下载需要版本的hadoop，我用的版本是hadoop-2.9.1

安装到5台机器上

master1  master2上安装namenode

master1  master2上配置resourcemanager

slave1   slave2   slave3上安装datanode

slave1   slave2   slave3上配置journalnode

slave1   slave2   slave3上配置nodemanager

1、将文件下载到、opt/workspace/目录下

2、解压缩

tar -zxvf hadoop-2.9..tar.gz

3、进行文件配置

对hadoop-env.sh   mapred-site.xml   hdfs-site.xml   yarn-site.xml   core-site.xml   slaves进行修改

（1）对core-site.xml进行配置

<?xml version="1.0" encoding="UTF-8"?>

<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>

（2）对hadoop-env.sh进行配置  添加

export JAVA_HOME=/opt/workspace/jdk1.8
有需要时才添加端口，不是22默认端口

export HADOOP_SSH_OPTS="-p 61333"

（3）对mapred-site.xml进行配置

<?xml version="1.0"?>

<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>

（6）修改slaves文件

配置完成

二、启动服务

1、首先启动5台服务器的zookeeper服务

cd /opt/workspace/zookeeper/zookeeper-3.4.

bin/zkServer.sh

2、slave1  slave2  slave3 上启动journalnode

[root@slave1 hadoop-2.9.]# sbin/hadoop-daemon.sh start journalnode
[root@slave2 hadoop-2.9.]# sbin/hadoop-daemon.sh start journalnode
[root@slave3 hadoop-2.9.]# sbin/hadoop-daemon.sh start journalnode

3、对master1进行格式化

[root@master1 hadoop-2.9.]# bin/hdfs namenode -format

4、master2进行元数据同步

[root@master2 hadoop-2.9.]# bin/hdfs namenode -bootstrapStandby

5、启动hadoop

[root@master1 hadoop-2.9.]# sbin/start-dfs.sh

6、启动resourcemanager

[root@master1 hadoop-2.9.]# sbin/start-yarn.sh

master2上手动启动resourcemanager

[root@master1 hadoop-2.9.]# sbin/yarn-daemon.sh start resourcemanager

7、成功启动服务后的截图

三、HA功能测试

问题解决：

在进行启动时，出现22端口拒绝访问，因为22端口为默认ssh访问端口，而我们的服务器不是22，所以需要修改一下

在hadoop-env.sh文件中添加

export HADOOP_SSH_OPTS="-p 61333"

防火墙问题：进行操作时需要将机器的防火墙关闭

[root@master1 bin]# systemctl start firewalld.service  #启动firewall

[root@master1 bin]# systemctl stop firewalld.service   #停止firewall

[root@master1 bin]# systemctl disable firewalld.service   #禁止firewall开机启动
