Windows 10缺少hadoop安装 [英] Missing hadoop installation for Windows 10

问题描述

我已在Windows 10上成功安装了Hadoop 2.8.1.现在，我正在尝试安装Hive 2.1版.当我尝试启动配置单元时，出现以下错误:

I successfully installed Hadoop 2.8.1 on Windows 10. Now I'm trying to install Hive version 2.1. When I try to start hive I receive the following error:

我在环境变量中将HADOOP_HOME设置为D:\ Hadoop-2.8.1 \ bin并添加到路径系统变量中.我是否必须在配置单元文件中指定此路径?

I have HADOOP_HOME set to D:\Hadoop-2.8.1\bin in the environment variables and added to the path system variable. Do I have to specify this path in a hive file?

推荐答案

J Skinner，

J Skinner,

您错误地设置了HADOOP_HOME.

You have wrongly set HADOOP_HOME.

在用户变量"中，将HADOOP_HOME配置为以下值.

In User variables, configure HADOOP_HOME with following value.

HADOOP_HOME-->D:\Hadoop-2.8.1

在系统变量中，在现有路径值之外添加以下值.

In System variables, add following value in addition of existing path value.

path--><Existing path values>;D:\Hadoop-2.8.1\bin;

如果您不满意上面的配置，请尝试以下方法.

If you not ok with that above configurations just try below way.

打开cmd提示，只需通过设置路径和位置来设置位置.

Open cmd prompt, Just set home by setting path and home.

C:>set HADOOP_HOME=D:\Hadoop-2.8.1

C:>set PATH=%PATH%;%HADOOP_HOME%\bin

现在从同一cmd提示符启动hadoop服务，然后转到配置单元外壳.

Now start hadoop services from same cmd prompt and then go to hive shell.

希望这对您有所帮助.
