Sqoop数据导出--头歌

1. start-all.sh
2. schematool -dbType mysql -initSchema

mysql -uroot -p123123 -h127.0.0.1

create database hdfsdb;

use hdfsdb;

create table fruit(fru_no int primary key,fru_name varchar(20),fru_price int,fru_address varchar(20));

exit;

vi text.txt

输入如下数据，我不直接打出来是因为数据有差别，肉眼看不见的差别，就是玄学问题。

hadoop fs -put text.txt /user

sqoop export --connect jdbc:mysql://127.0.0.1:3306/hdfsdb --username root --password 123123 --table fruit --export-dir /user/text.txt -m 1

mysql -uroot -p123123 -h127.0.0.1

use hdfsdb;

create table project(pro_no int primary key,pro_name varchar(20),pro_teacher varchar(20));

exit;

vi project.txt

:wq

hive

create table project (pro_no int,pro_name string, pro_teacher string) row format delimited fields terminated by ',' stored as textfile;

load data local inpath './project.txt' into table project;

exit;

sqoop export --connect jdbc:mysql://127.0.0.1:3306/hdfsdb --username root --password 123123 --table project --export-dir /opt/hive/warehouse/project -m 1 --input-fields-terminated-by ','
