hive导出数据

1.用insert，写到hdfs目录下，但是目录好像要由hive用户创建才可以，否则会报错

INSERT OVERWRITE DIRECTORY '/tmp/test1029_tmp' ROW FORMAT DELIMITED FIELDS TERMINATED by ',' select * from bank_info; 
+----------+-------+-----------+--------+------------+----------+
| acc_num | name | password | email | cellphone | balance |
+----------+-------+-----------+--------+------------+----------+
+----------+-------+-----------+--------+------------+----------+
No rows selected (0.947 seconds)

 

2.beeline客户端查询后写到本地

beeline -u jdbc:hive2://localhost:10000/ana --silent=true --outputformat=csv --showHeader=false -e "select a.* from last_30day limit 10" > out.csv
