Posted 2022-12-05 wyju

1.sqoop的下载地址

https://mirrors.tuna.tsinghua.edu.cn/apache/sqoop/1.4.7/sqoop-1.4.7.bin__hadoop-2.6.0.tar.gz 

2.上传sqoop

3.解压sqoop

sudo tar -zxvf sqoop-1.4.7.bin__hadoop-2.6.0.tar.gz -C /usr/local/

4.进入/usr/local目录

cd /usr/local

5.将解压后的sqoop-1.4.7.bin__hadoop-2.6.0目录重命名为sqoop

sudo mv sqoop-1.4.7.bin__hadoop-2.6.0/ sqoop

6.授权当前用户hadoop拥有sqoop目录的所有者权限

sudo chown -R hadoop:hadoop sqoop/

7.进入到sqoop目录下的conf里面

 cd /usr/local/sqoop/conf/

8.重命名sqoop-env-template.sh为sqoop-env.sh

 mv sqoop-env-template.sh sqoop-env.sh

9.修改配置sqoop-env.sh,配置hadoop、hbase、zookeeper的安装目录

export HADOOP_COMMON_HOME=/usr/local/hadoop

#Set path to where hadoop-*-core.jar is available
export HADOOP_MAPRED_HOME=/usr/local/hadoop

#set the path to where bin/hbase is available
export HBASE_HOME=/usr/local/hbase

#Set the path to where bin/hive is available
export HIVE_HOME=/usr/local/hive

#Set the path for where zookeper config dir is
export ZOOCFGDIR=/usr/local/zookeeper

10.进入到sqoop的lib目录下，把mysql-connector-java-5.1.47.jar驱动上传到lib中

 cd /usr/local/sqoop/lib/

11.拷贝hive的jar包到lib的目录中

cp /usr/local/hive/lib/hive-common-2.3.7.jar /usr/local/sqoop/lib/

12.编辑环境变量

a.进入环境变量

vim ~/.bashrc

b.添加以下内容

export SQOOP_HOME=/usr/local/sqoop
export PATH=$PATH:$SQOOP_HOME/bin

c.使环境变量生效

source ~/.bashrc

13.验证是否成功

sqoop version

使用sqoop之前的准备

1.启动zookeeper（三台都要启动）

zkServer.sh start

2.启动hadoop（在master上启动）

start-all.sh 

3.启动hbase（在master上）

 start-hbase.sh 

4.所有的节点

5.启动hive（在msater）

hiveserver2

6.启动mysql

 mysql -uroot -p123456

7.创建sqoop数据库

create database if not exists sqoop;

8.使用sqoop数据库

use sqoop;

9.创建表

CREATE TABLE IF NOT EXISTS `student`(
`id` int PRIMARY KEY COMMENT '编号',
	`name` varchar(20) COMMENT '名字',
	`age` int COMMENT '年龄'
)COMMENT '学生表';

10.插入数据

INSERT INTO student VALUES(1, 'zhangsan', 20);
INSERT INTO student VALUES(2, 'lisi', 24);
INSERT INTO student VALUES(3, 'wangwu', 18);
INSERT INTO student VALUES(4, 'zhaoliui', 22);

11.把mysql中student表中的数据导入到hdfs上

sqoop import --connect jdbc:mysql://localhost:3306/sqoop --username root --password 123456 --table student --target-dir /user/student --delete-target-dir -m 1

12.查看是否成功

hdfs dfs -cat /user/student/part-m-00000
