The Execute Hadoop command in the Windows environment appears Error:java_home is incorrectly set please update D:\SoftWare\hadoop-2.6.0\conf\ Hadoop-env.cmd the wrong solution (graphic and detailed)

Not much to say, directly on the dry goods!

Guide

Install Hadoop under win
Everyone, do not underestimate win under the installation of Big data components and use played Dubbo and disconf friends, all know that in win under the installation of zookeeper is often the Disconf learning series of the entire network the most detailed latest stable disconf deployment (based on Windows7 /8/10) (detailed) Disconf Learning series of the full network of the latest stable disconf deployment (based on Ubuntu14.04/ 16.04) (detailed) how to properly install zookeeper in Windows to run the service (blogger recommended) (graphic)

　　Question Details

For example, under Win cmd, execute the following command, will appear

Someone would be very curious to say

First hit the next java-version, right AH.

C:\users\lenovo>java-"1.8.0_66"1.8. 0_66-   - 25.66-B18, mixed mode) C:\Users\lenovo>

See Hadoop_home's system environment variables, yes, that's why? And listen to me as follows slowly.

Problem analysis

In this case, your JDK is installed under the C drive, and if it is a non-C drive, it will not normally happen.

　　　　Workaround (If your JDK is installed on the C drive)

This sub-condition, if your JDK is installed on the C drive, for example to keep the default

　　

The

　　

Found it

　　Method 1. Use path substitution

C:\progra~1\java\jdk1.8.0_66

　　Because PROGRA~1 is the abbreviation for the C:\Program Files directory in DOS file name mode.
Filenames and folder names longer than 8 characters are simplified to the first 6 valid characters, followed by a ~2,~3 with the same name,

Set java_home=c:\progra~1\java\jdk1. 8. 0_66

　　Method 2, enclose it in quotation marks.

Set java_home= "C:\Program Files" \java\jdk1.8.0_66

C:\users\lenovo>Hadoop version'C:\Program'is not an internal or external command, or a program or batch file that can be run. Hadoop2.6.0Subversion https://git-wip-us.apache.org/repos/asf/hadoop.git-r E3496499ECB8D220FBA99DC5ED4C99C8F9E33BB1Compiled by Jenkins on the- One-13t21:10zcompiled with Protoc2.5.0From source with checksum 18e43357c8f927c0695f1e9522859d6athis command is runusing/d:/software/hadoop-2.6.0/share/hadoop/common/hadoop-common-2.6.0. Jarc:\users\lenovo>

　　　　Workaround (If your JDK is installed on a non-C drive)

　　　　　There is no need to modify the hadoop-env.cmd.

For example, your installation in E:\software\jdk1.8

However, if your JDK is such as the program files installed under the D drive, It is D:\Program files "\java\jdk1.7.0_03, but why not?"

Set Java_home="D:\Program Files"\java\jdk1. 7. 0_03

Can only say, perhaps at present is a debug bar. It is recommended that the JDK is installed by default in the C drive letter.
