使用 sqoop 将mysql数据导入到hive（import）

CREATE TABLE `sqoop_test` (
`id` int(11) DEFAULT NULL,
`name` varchar(255) DEFAULT NULL,
`age` int(11) DEFAULT NULL
) ENGINE=InnoDB DEFAULT CHARSET=latin1

hive> create external table sqoop_test(id int,name string,age int)
> ROW FORMAT DELIMITED
> FIELDS TERMINATED BY ‘,‘
> STORED AS TEXTFILE
> location ‘/user/hive/external/sqoop_test‘;
OK
