我是靠谱客的博主时尚豌豆，最近开发中收集的这篇文章主要介绍大数据7_05_Sqoop导入数据到hdfs，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

5 导入数据到hdfs

[atguigu@hadoop102 bin]$ vim mysql_to_hdfs.sh

声明变量：APP和sqoop

昨天的日期：date --help查看date的使用说明

date -d ‘yesterday’
date -d ‘-1 day’
放在shell中需要加一个`号或者放在$()内
echo $(date -d '-1 day')
echo `date -d '-1 day'`
第一个参数是：first表示第一次到数据，对于一些仅仅上传一次的特殊情况的同步策略。仅仅上传这一次

第二个参数是：时间，first + 数据库内表的时间。默认是当前的时间日期-1

#! /bin/bash

APP=gmall
sqoop=/opt/module/sqoop/bin/sqoop

if [ -n "$2" ] ;then
    do_date=$2
else
    do_date=`date -d '-1 day' +%F`
fi

import_data(){
$sqoop import 
--connect jdbc:mysql://hadoop102:3306/$APP 
--username root 
--password 123456 
--target-dir /origin_data/$APP/db/$1/$do_date
