Hive创建内部表详细步骤

1.创建内部表SQL语句

create table emp_in(
empno int,
ename string,
job string,
mgr int,
hiredate string,
sal double,
comm double,
deptno int)
row format delimited fields terminated by ',';

先将emp.txt文件上传到linux本地根目录下（/emp.txt）和HDFS文件系统的根目录下（/emp.txt）。

② 将Linux本地数据导入至emp_in表（复制操作）

load data local inpath '/emp.txt' overwrite into table emp_in;

③ 将HDFS数据导入至emp_in表（剪切操作）

load data inpath '/emp.txt' overwrite into table emp_in;

注意：emp.txt文件的内容信息如下：
