我是新来的 Hadoop . 我已经在中创建了employee表 Hive 使用文本文件加载数据,现在我尝试加载保存在表中的数据,但得到以下结果。我到处找,但什么也没找到。有人能帮我吗?

hive> select * from employee;
-chgrp: 'LONEWOLF\Sudarshan' does not match expected pattern for group

Generic options supported are
-conf <configuration file>     specify an application configuration file
-D <property=value>            use value for given property
-fs <file:///|hdfs://namenode:port> specify default filesystem URL to use, overrides 'fs.defaultFS' 
 property from configurations.
-jt <local|resourcemanager:port>    specify a ResourceManager
-files <comma separated list of files>    specify comma separated files to be copied to the map 
 reduce cluster
-libjars <comma separated list of jars>    specify comma separated jar files to include in the 
 classpath.
-archives <comma separated list of archives>    specify comma separated archives to be unarchived on 
the compute machines.

The general command line syntax is
command [genericOptions] [commandOptions]

Usage: hadoop fs [generic options] -chgrp [-R] GROUP PATH...
OK

奇怪的是,它占用了4行空间,显示为空白。
不明白发生了什么?
表创建:

create table employee (Id int, Name string , Salary float)  
    row format delimited  
    fields terminated by ',' ;

在表中加载数据:

load data local inpath 'C:\employee.txt' into table employee;
``` `employee.txt` 文件

1 "Anurag" 40000.0
2 "Ayush" 42000.0
3 "Akhil" 44000.0
4 "Aarav" 46000.0

7d7tgy0s1#

创建表时
',' delimited fields ,这意味着源必须有字段以“,”分隔的行
您的源文件

1 "Anurag" 40000.0
2 "Ayush" 42000.0
3 "Akhil" 44000.0
4 "Aarav" 46000.0

是一个空格分隔的字段,应该是

1,"Anurag",40000.0
2,"Ayush",42000.0
3,"Akhil",44000.0
4,"Aarav",46000.0

或者您创建的表应该是

create table employee (Id int, Name string , Salary float)  
row format delimited  
fields terminated by ' ' ;
