2、hive的基本操作

1、创建表

 hive>CREATE TABLE userTables(id INT,name STRING);

或者

hive> CREATE TABLE userTables(id int, name string) ROW FORMAT DELIMITED FIELDS TERMINATED BY ‘ ‘ LINES TERMINATED BY ‘\n‘ STORED AS TEXTFILE;

其中TERMINATED BY ‘ ‘指定了数据分隔符是一个空格

创建一个新表，结构与其他一样

hive> create table new_table like testUser;

2、创建分区表

hive> create table logs(ts bigint,line string) partitioned by (dt String,country String)ROW FORMAT DELIMITED FIELDS TERMINATED BY ‘ ‘ LINES TERMINATED BY ‘\n‘ STORED AS TEXTFILE;

加载分区表数据：

hive> load data local inpath ‘/home/test.txt‘ into table logs partition (dt=‘2017-07-20‘,country=‘GB‘);
