sqoop 安装与配置使用

hive 与 mysql/pgsql 数据传递

sqoop 安装

安装包 上传至 hive-server.

$ docker cp mysql-connector-java-5.1.28.jar dc387ff5c56d:/opt/mysql-connector-java-5.1.28.jar
$ docker cp sqoop-1.4.6.bin__hadoop-2.0.4-alpha.tar.gz dc387ff5c56d:/opt/sqoop-1.4.6.bin__hadoop-2.0.4-alpha.tar.gz

进入 hive-server 安装 sqoop

$ docker exec -it dc387ff5c56d /bin/bash
# tar -zxvf sqoop-1.4.6.bin__hadoop-2.0.4-alpha.tar.gz
# rm sqoop-1.4.6.bin__hadoop-2.0.4-alpha.tar.gz 
# mv sqoop-1.4.6.bin__hadoop-2.0.4-alpha/ sqoop


# mv mysql-connector-java-5.1.28.jar sqoop/lib/mysql-connector-java-5.1.28.jar
# cp sqoop/conf/sqoop-env-template.sh sqoop/conf/sqoop-env.sh
# vim sqoop/conf/sqoop-env.sh

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

sqoop 将sqoop 数据导入

# /opt/sqoop/bin/sqoop list-databases --connect jdbc:mysql://192.168.20.204:3306/ --username ad_user --password 'dl_ad!@#123'
