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:
代码语言:javascript复制 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:
代码语言:javascript复制 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
代码语言:javascript复制 mv sqoop-env-template.sh sqoop-env.sh
2) 修改配置文件
代码语言:javascript复制vim sqoop-env.sh
增加如下内容
代码语言:javascript复制 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
代码语言:javascript复制 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:
代码语言:javascript复制 bin/sqoop help
出现一些Warning警告(警告信息已省略),并伴随着帮助命令的输出:
代码语言:javascript复制Available commands:
codegen Generate code to interact with database records
create-hive-table Import a table definition into Hive
eval Evaluate a SQL statement and display the results
export Export an HDFS directory to a database table
help List available commands
import Import a table from a database to HDFS
import-all-tables Import tables from a database to HDFS
import-mainframe Import datasets from a mainframe server to HDFS
job Work with saved jobs
list-databases List available databases on a server
list-tables List available tables in a database
merge Merge results of incremental imports
metastore Run a standalone Sqoop metastore
version Display version information
5 测试Sqoop是否能够成功连接数据库
代码语言:javascript复制bin/sqoop list-databases --connect jdbc:mysql://hadoop102:3306/ --username root --password 000000
