3、hive -f 用法

[root@cloud1 hive-0.13.1]# touch hfile.sql
[root@cloud1 hive-0.13.1]# vi hfile.sql
select * from default.student ; 
bin/hive -f /opt/hive-0.13.1/hfile.sql
[root@cloud1 hive-0.13.1]# bin/hive -f /opt/hive-0.13.1/hfile.sql

4、hive -i 用法：(这里占时还没有例子)

* bin/hive -i xx
-i <filename>                    Initialization SQL file
eg:
add jar xxx.jar
add file xxx
create temporary function my_lower as ....
bin/hive -i hive-init.sql
