hive 簡單shell操作

1，建表

create table test(name string );

2，查看所有表

show tables;

3,本地文件上傳

b.txt

 

haha
xiaoming
lilei
hanmeimei
 

load data local inpath '/home/b.txt' into table test;

4，查看錶數據

select * from test;

 

5,beenline

#後臺啓動metastore服務和hiveserver2服務
hive --service metastore > metastore.log 2>&1 &
hive --service hiveserver2 > hiveserver2.log 2>&1 &
或者
nohup hive --service metastore&
nohup hive --service hiveserver2&
使用beeline命令行連接：
beeline
!connect jdbc:hive2://zdh-9:10000/default
用戶名和密碼都爲空，直接回車
#成功進入beeline連接jdbc數據庫
show databases;
show tables;
#退出連接
!q
操作說明：
#連接成功，顯示一個default默認數據庫和一個student表。

 

sparkSQl shell操作

1，建表，上傳數據，都與hive完全一樣

,2，依靠ranger，實現數據脫敏
