[root@host ~]# hive -e 'use gamedw;show tables'

3.执行文件

同样

 hive -i  /root/tmpdata/hive.sql  也可以执行hql同时开启cli

hive  -hivevar 传递参数

[root@host ~]# cat /root/tmpdata/hivevar.sql
select * from gamedw.v_cust where sex=${varsex} and age>${varage};

[root@host ~]# hive -hivevar varsex=0 -hivevar varage=20 -f /root/tmpdata/hivevar.sql
