I am trying to install Hadoop 2.6 in Windows 10, while doing that i'm getting below error
C:\hadoop-2.6.2\bin>hadoop -version
The system cannot find the path specified.
Error: JAVA_HOME is incorrectly set.
Please update C:\hadoop-2.6.2\conf\hadoop-env.cmd
'-Xmx512m' is not recognized as an internal or external command, operable program or batch file.
I had the same issue, and it can be fixed by 2 ways.
check your environment variable, if JAVA_HOME setup for the user or not and path setup correctly or not.
Please remove system JAVA_HOME and setup for user.
Go to command line and setup Java Home and Path.
set JAVA_HOME = your jdk home directory
set PATH = %JAVA_HOME%/bin

Whenever I type mvn -version to check version installed it says that "mvn is not an internal or external command" in cmd.
I have added images to show that I have added environmental variable and the path. do check those and help out.
UPDATE :
After having been told that i have to remove \bin from environment variable of both JAVA_HOME and MAVEN_HOME. now I'm getting error in cmd as JAVA_HOME is not defined.

Your MVN_HOME should be the maven root folder (G:\compressed\apache-maven-3.8.4) not up to the bin folder.
Change MVN_HOME variable to G:\compressed\apache-maven-3.8.4 then open a new cmd prompt then the command will work.
I'm trying to run the following command through powershell to install ElastiSearch but it the service batch file can't find the JAVA_HOME path.
I've added JAVA_HOME to my system variables and I can see the path when I echo JAVA_HOME through command line. Not sure why the batch file is pointing to an empty path.

Obviously, your variable in system variables JAVA_HOME is pointing to the wrong location. Make sure to provide the right path for JAVA_HOME to be: .\Java\jdk1.8.0

I had downloaded spark-2.0.1-bin-hadoop2.7 and installed it. I installed JAVA and set JAVA_HOME in System Variables.
But in running I have this Error:
How to it can be fixed ?
I think the problem is with whitespaces in your path.
Try to place downloaded spark in for example. F:\Msc\BigData\BigDataSeminar\Spark\
Also check whether SPARK_HOME, JAVA_HOME and HADOOP_HOME are placed in the path without whitespaces.
following the docs here: http://attester.ariatemplates.com/usage/phantom.html, I am trying to install phantomjs on my windows machine.
I tried adding multiple lines to my Path system variable, and yet, I get the same error in the command prompt when I type in phantomjs --version.
" 'phantomjs' is not recognized as an internal or external command, operable program or batch file."
I added the phantomjs.exe to C:\phantomjs\bin\, and added C:\phantomjs\bin\phantomjs to the path, and any variation that I could think of, such as:
C:\phantomjs\bin\phantomjs.exe\; C:\phantomjs\bin; C:\phantomjs\bin\phantomjs\;
How am I not installing this right?
You don't need to put all the directories to the environment PATH variable.
Add only following to your path and restart your command prompt.
C:\phantomjs\bin\
Add phantomjs.exe to C:\Windows\System32 folder.
