Sqoop 只用在一台有 HIVE 的服务器上安装即可

这里我选择的是 slave2

下载安装

Apacha Sqoop 官方下载地址

http://archive.apache.org/dist/sqoop/1.4.7/

1. 下载上传至 /opt/software


2. 解压至 /opt/servers

tar -zxvf sqoop-1.4.7.bin__hadoop-2.6.0.tar.gz -C /opt/servers
cd /opt/servers
mv sqoop-1.4.7.bin__hadoop-2.6.0 sqoop-1.4.7


设置环境变量

# Sqoop
export SQOOP_HOME=/opt/servers/sqoop-1.4.7
export PATH=$PATH:$SQOOP_HOME/bin


使其生效

source /etc/profile


创建并修改配置文件

cd $SQOOP_HOME/conf
cp sqoop-env-template.sh sqoop-env.sh


vim sqoop-env.sh

在文件末尾增加：

export HADOOP_COMMON_HOME=/opt/servers/hadoop-2.10.1
export HADOOP_MAPRED_HOME=/opt/servers/hadoop-2.10.1
export HIVE_HOME=/opt/servers/hive-2.3.9


链接 Jar 包

JDBC

注意自己的JDBC版本

ln -s /opt/servers/hive-2.3.9/lib/mysql-connector-java-8.0.26.jar /opt/servers/sqoop-1.4.7/lib


hive-common.jar

将$HIVE_HOME/lib下的hive-common-2.3.7.jar,拷贝到$SQOOP_HOME/lib目录下。如不拷贝在MySQL往Hive导数据的时候将会出现错误：ClassNotFoundException:org.apache.hadoop.hive.conf.HiveConf

ln -s /opt/servers/hive-2.3.9/lib/hive-common-2.3.9.jar /opt/servers/sqoop-1.4.7/lib


验证安装

sqoop version


数据导入

懒了，有需要在我补充上去。。。。

数据导出Mysql

CREATE TABLE jobdata_origin (
city VARCHAR ( 100 ) COMMENT '城市',
salary VARCHAR ( 100 ) COMMENT '薪资',
company VARCHAR ( 100 ) COMMENT '福利',
`kill` VARCHAR ( 100 ) COMMENT '技能'
) COMMENT "原始职位数据表";


sqoop export \
--connect jdbc:mysql://slave2:3306/fengrengui \
--username hive \
--password 0000 \
--table jobdata_origin \
-m 1 \
--export-dir /user/hive/warehouse/fengrengui.db/ods_jobdata_origin \n
--input-fields-terminated-by ","


导出成功后到mysql查看是否有数据

SELECT * FROM jobdata_origin;
