下面介紹幾種常用的匯入資料到hive的方式

1. 載入本地檔案到hive

     load data local inpath '/data/hive/student_info.txt' into table default.student_info 

2. 載入hdfs檔案到hive中

    load data inpath '/data/hive/student_info.txt' into table default.student_info

3. 載入資料覆蓋表中已有的資料

    load data inpath '/data/hive/student_info.txt' overwrite into table default.student_info
 

4. 建立表的時候通過insert 插入資料

create table default.student_info_c1 like student_info;
insert into table default.student_info_c1 select * from  default.student_info;

5. 建立表的時候通過location 載入

create table user_info_t1(
    id      int
   ,name    string
   ,hobby   array<string>
   ,add     map<String,string>
)
STORED AS TEXTFILE
row format delimited
fields terminated by ','
collection items terminated by '-'
map keys terminated by ':'
 LOCATION '/hive/data/ ';
