1.insert 将查询结果直接导出到本地
insert overwrite local directory "kg/qiaoruihua/hive/emp" select * from student; insert overwrite local directory "kg/qiaoruihua/hive/emp2" row format delimited fields terminated by "," select * from student;
2.insert 将查询结果导出hdfs
insert overwrite directory "/user/hive/warehouse/emp" select * from student; insert overwrite directory "/user/hive/warehouse/emp2" row format delimited fields terminated by "," select * from student;
3.利用shell命令导出
hive -e "select * from student" > "/opt/module/datas/student.txt"
4.利用hadoop导出到本地
dfs -get /user/hive/warehouse/student/student.txt /opt/module/datas/student.txt
5.利用export导出
