选中 jdk 安装包右键解压到当前文件夹

deepin jdk

选择解压缩后的jdk目录右键重命名

deepin jdk

将 jdk 安装包重命名为 jdk-8

选中 hadoop 安装包右键解压到当前文件夹

选中 hadoop 解压后的目录右键重命名

将 hadoop 安装包重命名为 hadoop-3

配置ssh免密钥登录

创建本地秘钥并将公共秘钥写入认证文件

ssh-keygen -t rsa -P '' -f ~/.ssh/id_rsa
cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
# 或者
ssh-copy-id hadoop

deepin 免密钥

Hadoop初始化

# 格式化文件系统
hdfs namenode -format
# 启动 NameNode SecondaryNameNode DataNode 
start-dfs.sh
# 查看启动进程
jps
# 看到 DataNode SecondaryNameNode NameNode 三个进程代表启动成功

hdfs

# 启动 ResourceManager daemon 和 NodeManager
start-yarn.sh
# 看到 DataNode NodeManager SecondaryNameNode NameNode ResourceManager 五个进程代表启动成功

hadoop

重点提示：

# 关机之前 依关闭服务
stop-yarn.sh
stop-dfs.sh
# 开机后 依次开启服务
start-dfs.sh
start-yarn.sh

或者

# 关机之前关闭服务
stop-all.sh
# 开机后开启服务
start-all.sh

#jps 检查进程正常后开启胡哦关闭在再做其它操作
