1.使用非交互式执行hive语句
bin/hive -e <quoted-query-string>
eg:
bin/hive -e "select * from default.student ;"
2.运行存放hive语句的文件
bin/hive -f <filename>
eg:
$ echo "select * from db_hive.student ;" > hivef.sql
$ bin/hive -f /opt/datas/hivef.sql
$ bin/hive -f /opt/datas/hivef.sql > /opt/datas/hivef-res.txt
3.与用户udf相互使用
bin/hive -i <filename>
4.在hive cli命令窗口中如何查看hdfs文件系统
hive (default)> dfs -ls / ;
5.在hive cli命令窗口中如何查看本地文件系统
hive (default)> !ls /opt/datas ;
