本文详细介绍了如何使用Hive构建表结构、加载文本数据、执行SQL查询及解决错误过程，涵盖Hive的基本操作及数据处理技巧。

1,建表语句

(id int, name string,

age int, tel string)

ROW FORMAT DELIMITED

FIELDS TERMINATED BY '\t'

STORED AS TEXTFILE;

2,url.txt文本

1	wyp     25      13188888888888
2       test    30      13888888888888
3       zs      34      899314121

3,加载数据

load data local inpath '/data/projects/clusters/test/url.txt' into table joeyon;

4,查询 select * from joeyon;

hive> select * from joeyon;                                                           
OK
1	wyp	25	13188888888888
2	test	30	13888888888888
3	zs	34	899314121

5,命令行信息

ive> select * from joeyon;     
FAILED: Error in semantic analysis: Line 1:14 Table not found 'joeyon'
hive> create table joeyon
    > 
    > (id int, name string,
