sqoop安装教程

1 下载并解压

1）下载地址：http://mirrors.hust.edu.cn/apache/sqoop/1.4.6/

2）上传安装包sqoop-1.4.6.bin__hadoop-2.0.4-alpha.tar.gz到hadoop102的/opt/software路径中

3）解压sqoop安装包到指定目录，如：

[molly@hadoop102 software]$ tar -zxf sqoop-1.4.6.bin__hadoop-2.0.4-alpha.tar.gz -C /opt/module/

4）解压sqoop安装包到指定目录，如：

[molly@hadoop102 module]$ mv sqoop-1.4.6.bin__hadoop-2.0.4-alpha/ sqoop

2 修改配置文件

1. 进入到/opt/module/sqoop/conf目录，重命名配置文件

[molly@hadoop102 conf]$ mv sqoop-env-template.sh sqoop-env.sh

2. 修改配置文件

[molly@hadoop102 conf]$ vim sqoop-env.sh 

增加如下内容

export HADOOP_COMMON_HOME=/opt/module/hadoop-3.1.3
export HADOOP_MAPRED_HOME=/opt/module/hadoop-3.1.3
export HIVE_HOME=/opt/module/hive
export ZOOKEEPER_HOME=/opt/module/zookeeper-3.5.7
export ZOOCFGDIR=/opt/module/zookeeper-3.5.7/conf

3 拷贝JDBC驱动

1）将mysql-connector-java-5.1.48.jar 上传到/opt/software路径

2）进入到/opt/software/路径，拷贝jdbc驱动到sqoop的lib目录下。

[molly@hadoop102 software]$ cp mysql-connector-java-5.1.48.jar /opt/module/sqoop/lib/

4 验证Sqoop

我们可以通过某一个command来验证sqoop配置是否正确：

[molly@hadoop102 sqoop]$ bin/sqoop help
