Installing Spark on Windows not working

I am trying to install Apache Spark on my Windows 10 computer. My first step to install Spark was to download Java from here it was then downloaded through this path: C:\Program Files (x86)\Java the one folder that was downloaded during this installation was: \jre1.8.0_151
Next I installed the JDK from here and downloaded the windows x86 version. I used the same path as above in the Java folder to download it. After it was done I had two folders inside the Java folder: jdk1.8.0_151 and jre1.8.0_151
Afterwards, I set the JAVA_HOME variable to point to C:\PROGRA~1(x86)\Java\jdk1.8.0_151 and in Path I added %JAVA_HOME% I then installed Scala from here and downloaded the Scala binaries for Windows. The environment path was added in path as: C:\PROGRA~1(x86)\scala\bin
Next I installed Spark from here and installed spark-2.2.1-bin-hadoop2.7.tgz Afterwards, I placed this folder here D:\spark-2.2.1-bin-hadoop2.7I then added the environment variable as SPARK_HOME with the path: D:\spark-2.2.1-bin-hadoop2.7\bin and I then updated path to %SPARK_HOME%\bin
Finally I tried to see if everything was installed. I typed java -version and the correct java was installed. I then typed scala and scala was open for me to type in expressions and such. I then typed in spark-shell but I got this error:
'spark-shell' is not recognized as an internal or external command,
operable program or batch file.
What am I doing wrong that is not making spark open? Please note: I am using cmd for everything.

It looks like you set your %SPARK_HOME% to a wrong place and thus when "I then updated path to %SPARK_HOME%\bin" it resulted in adding D:\spark-2.2.1-bin-hadoop2.7\bin\bin with double \bin which is obviously wrong. %SPARK_HOME% should be without \bin.
Generally you can test your environment variables by calling echo %PATH% in the command line or SET to show all of them

Unable to Start Talend Tool JAVA Version incompatibility

My Talend tool version is 5.6. As mentioned in Talend documentation it needs Java Runtime Environment 7 i.e jdk1.7, which is installed - along with set java_home in my environment variables. As per me it should work.
However I have jdk1.8 installed too, but I'm correctly pointing jdk1.7 path at environment variable.
Alternatively I have tried giving jdk1.7 path in Talend's Talend-Studio-win-x86_64.ini file. It's still giving me error.
Below is snapshot: in cmd the installed version shows jdk1.8 where in echo %JAVA_HOME% it shows path of jdk1.7
While starting tool this error comes:

Create a batch file with the following command:
Talend-Studio-win-x86_64.exe -vm "[jdk path]\bin"
Then start the studio by executing this batch.

Talend is based on eclipse, so you can set the java vm to use in the ini-file. (Sorry, I don't have an installation here right now, I think it is called talend.ini - nevertheless, it is located in talend's installation folder.)
Add the following to the top of the file:
-vm
[path to your java 7]/bin/javaw.exe

try to make changes in TOS_DI-win-x86_64.ini file
add line
-vm
C:\Program Files\Java\jdk-11.0.14\bin\javaw.exe
And update or confirm the version as below.
-Dosgi.requiredJavaVersion=11.0.14
Hope it'll help to fix the issue

Suppose you have talend in c:\talend and jdk1.7 is in C:\jdk1.7.
You can do like the following in windows environment.
Open command prompt.
Goto the bin folder location where jdk 1.7 is located. For example if you have jdk in C:\jdk1.7 then
cd\
cd C:\jdk1.7\bin
Then from bin folder of jdk type the full uri of the executable and hit enter.
In the above supposition c:\jdk1.7\bin>c:\talend\tos_di-xxxxx.exe
In the above statement tos_di-xxxxx.exe is the executable file depending on the os environment

Installing tizen in windows 7

I am trying to install tizen wearable sdk in windows 7 64bit. I have donwload the .exe however when I am trying to isntall it I am getting the following error:
error - Cannot execute Java even if it was installed. Check environment variable or Java version(over 1.6) please.
I have installed in my computer java 1.7.0_80. I have put to the path of the system C:\Program Files\Java\jre7\bin and in JAVA_HOME C:\Program Files\Java\jdk1.7.0_80
I have tried to follow the instructions from here here however I didn't mange to solve my issues.
EDIT: I followed the instructions from that link I went to cd\Users\AppData\Local\Temp and I run from there the command in console java -jar installmanager.jar. THe installation began normally. However, during the installation I got several errors.

I've had a few problems with the Tizen Wearable install too.
You can either make sure that you have Java in your path by going to a command prompt and typing java -version for example. If it works then Java is in your path. If it doesn't you have to fix it:
Win+Pause/SysRq then click on Advanced System Settings
Click on environment variables
Look for PATH and edit it
Add the path to your Java install (eg: C:\Program Files (x86)\Java\jre1.8.0_31)
Or run from the command line:
Go to a command line
cd to %TEMP%
Run Java by first entering the path to your java version (eg C:\Program Files (x86)\Java\jre1.8.0_31) then bin\java, so C:\Program Files (x86)\Java\jre1.8.0_31\bin\java.exe
If you are still having problems then edit the question to add more specific information so any other issues can be fixed.

Try to check if this directory is in the path too:
C:\ProgramData\Oracle\Java\javapath
and if there is links to missing java executables.
If this is the case, you can remove that folder to the path, replacing with the current java version you want, or fix the link from there.

It seems like the VBS script tried to delete a file that doesn't exist, you can go to the VBS file and go to the problem line, and check out which file was missing. Then decide what to do.
Maybe you should install the latest JDK, try the latest JDK and see if the problem can be solved.

Can't install Java JDK

Ok, this is embarrassing, but I can't install Java. I have no experience in Java so any help appreciated.
So as ussual I install Java JDK (The JRE I think is already there before) I have jre7 and jdk1.8.0.0_05
I have install it, but Java still not in my computer
Here's some desperate cmd check
>C:\>WHERE java
>INFO: Could not find files for the giving pattern
>C:\>java
>'java is not recognized as an internal or external command, operable program or batch file.
Where my java folder is C:\Program Files (x86)\Java\jdk1.8.0.0_5
On my desperation I created the variable JAVA_HOME on the given directory. Afterward, I tried this.
>C:\>echo %JAVA_HOME%
%JAVA_HOME%
I was expecting the cmd to echo the directory.
The variable PATHEXT has the following in it:
.COM;.EXE;.BAT;.CMD;.VBS;.VBE;.JS;.JSE;.WSF;.WSH;.MSC
Clariffication:
I tried to reinstall the Java Jdk Installer with Windows Installer, but no luck.
If this matters, I'm running from Windows 7.
I tried to learn from Here
After closer inspection, I can run java and javac after going all the way into the directory (so inputing java outside the bin will do nothing good)

Add C:\Program Files (x86)\Java\jdk1.8.0.0_5\bin to your PATH variable
Here is how mine is

I think you may have not added JAVA_HOME environment variable, and/or to PATH environment variable neither.
Give a read to this article
http://www3.ntu.edu.sg/home/ehchua/programming/howto/jdk_howto.html

Regarding you last comment, i think you should put the java directory right infront of all the other directory because, if you were to install another version of java it might not be used if you place it behind.
(For Advanced Users Only)
I suggested that you place the JDK bin directory in front of "c:\windows\system32" and "c:\windows". This is because some Windows systems may have an out-dated copy of JDK/JRE in these directories. Do a search for "java.exe", and you will be amazed by the findings.
You could read "Java Applications and Environment Variable" for more discussions about PATH environment variable.
I also recommend that you define an environment variable called JAVA_HOME, which contains the JDK installed directory, and include the JDK bin directory in the PATH via JAVA_HOME, i.e., PATH=%JAVA_HOME%\bin;.....

Why does java -version return an old version?

OS: Windows XP
I am using yuicompressor-2.4.2 to compress some CSS before uploading to my server.
But when I run it, the following exception appears:
Exception in thread "main" java.lang.UnsupportedClassVersionError:
com/yahoo/platform/yui/compressor/Bootstrap (Unsupported major.minor version 48.0)
So I think it's because of the JRE.
I typed in the command:
cmd: java -version
And it says:
java version "1.3.1_01"
But it should say 1.6.0_16, since I have installed the latest version.
What should I do to make Java use the latest version instead of the old one?

Set the environment variable JAVA_HOME pointing to the directory where you have jdk 1.6.0
set JAVA_HOME=your_path_to_jdk1.6
set PATH=%JAVA_HOME%/bin;.;..;%PATH%
That's from a command window. Also you can do it from "My PC > Properties > Advanced > Environment variables"

Go to the system32 directory C:\Windows\System32 and delete following 3 files
java.exe
javaw.exe
javaws.exe
Now create a JAVA_HOME environment variable with value={root path of your jdk installation} and add the path till bin folder of your jdk in the PATH environment variable.
Open a fresh command prompt and run java -version to confirm the change

If you are using windows 7/10 go to command prompt and type
where java
Delete all the symbolic link shows below other than your actual installation directory.
Even if correctly added all the environment variables still sometime you can get wrong versions especially when you have multiple version installed in your system and want to switch between them.

On Windows, the JRE installs a java executable in the Windows directory, which should be the first java in your path. This is just a wrapper that looks in the Windows Registry to find the Java home directory (should be "%SystemDrive%\Program Files\Java\jre6" for Java 6) and runs using the libraries there.
Run %SystemRoot%\system32\java -version and see what you get. If that is Java 6, you have entries in your path before %SystemRoot%\system32 (which really should be first). Either fix your %PATH% variable, or you'll have to be explicit whenever you want to run this version of Java.
If running that instance of java doesn't report Java 6, its not installed (correctly). Uninstall and try installing again.
If you are having trouble because of the PATH, it is because you or some software you installed monkeyed with it; I recommend using the default which is to have system32 first. Everything works fine if the defaults are used.
Also, %JAVA_HOME% is not used by the JRE itself at all. Some common Java applications like tomcat and ant honor the %JAVA_HOME% setting, so perhaps yuicompressor does too. But this is a de facto convention, not a standard.

after where java in Command prompt
for example
where java
C:\Program Files\Common Files\Oracle\Java\javapath
C:\Program Files\Java\jdk-11.0.10\bin\java.exe
delete C:\Program Files\Common Files\Oracle folder
then close all terminals and write java -version in the terminal. it will show the right version
worked for me

You should modify your PATH environment variable:
My PC > Right click > properties > Advanced > Environment variables
And modify "Path"
Append at the end the path to your 1.6 installation:
;C:\jdk1.6.xxx\bin
and remove the previous one if present.

Add %JAVA_HOME%/bin to your PATH environment variable where JAVA_HOME is set to your JRE6u16 directory

I had the same problem. In System Properties > Environment Variables > System Variables > PATH make sure there is no other path associated with Java. To make sure, type in and check Java paths.
where java
Re-open Command Prompt and type java -version again. I hope this helps.

first by the following command, you should be aware of .exe file which runs when you type java in the command prompt
where java
C:\Program Files\Common Files\Oracle\Java\javapath
C:\Program Files\Java\jdk-11.0.10\bin\java.exe
as you see above , cmd first reads java from
C:\Program Files\Common Files\Oracle\Java\javapath
so go to the path above and remove java files .
then it should work fine

You should check your PATH environment variable. It is possible that some application you have installed has put its version of the jre in front of yours in the path.

It looks like the older Java version is still on the system PATH environment variable (where the OS looks for commands) or JAVA_HOME (where yuicompressor may look for the java executable)
How those variables are changed depends on your operating system.
