问题描述
- hive无法进行条件查询
- 用hive可以建表，执行不加条件的查询可以，如select * from t_hive；如果加上条件进行查询则失败，如select * from t_hive where a>30;则失败；执行过程如下：
hive> show tables;
OK
t_hive
t_hive2
t_hive3
Time taken: 0.058 seconds Fetched: 3 row(s)
hive> select * from t_hive;
OK
16 2 3
61 12 13
41 2 31
17 21 3
71 2 31
1 12 34
11 2 34
Time taken: 0.156 seconds Fetched: 7 row(s)
hive> select * from t_hive where a>30;
