I am trying to get pyspark setup for windows. I have java, python, Hadoop, and spark all setup and environmental variables I believe are setup as I've been instructed elsewhere. In fact, I am able to run this from the command prompt:
pyspark.cmd
And it will load up the pyspark interpreter. However, I should be able to run pyspark unqualified (without the .cmd), and python importing won't work otherwise. It does not matter whether I navigate directly to spark\bin or not, because I do have spark\bin added to the PATH already.
.cmd is listed in my PATHEXT variable, so I don't get why the pyspark command by itself doesn't work.
Thanks for any help.
While I still don't know exactly why, I think the issue somehow stemmed out of how I unzipped the spark tar file. Within the spark\bin folder, I was unable to run any .cmd programs without the .cmd extension included. But I could do that in basically any other folder. I redid the unzip and the problem no longer existed.

I installed spark and am trying to run a file 'train.py' in the directory, '/home/xxx/Desktop/BD_Project', in shell using the following command:
$SPARK_HOME/bin/spark-submit /home/xxx/Desktop/BD_Project/train.py > output.txt
My teammates who used the same page that I did for spark installations have no problem when running this. However, it throws up the following error for me:
bash: /bin/spark-submit: No such file or directory
You need to set your SPARK_HOME to where your spark is installed, typically its in /usr/local/spark/bin/bin/spark-submit
Before you set it make sure where spark is installed by going to the directory.
You can set it like this before running your command :
export SPARK_HOME=/usr/local/spark/bin/bin/spark-submit
If you are homebrew user, setting your SPARK_HOME to
/opt/homebrew/Cellar/apache-spark/3.3.1/libexec"
would solve. Sorry for too late responding. Hoping this would help someone with this odd error.
I have successfully installed pyspark using anaconda and configured paths in the .bashrc file.
Post typing pyspark command, it opens Jupyter-notebook in which python code is working properly. Like, print "Hello" etc.
But when I execute the Pyspark commands like collect(), take(5) etc, it gives an error that "Cannot run program '/usr/bin/Python-3.7.4". Permission denied.
It is referring wrong directory, as Python-3.7.4 is installed in the Anaconda directory.
Is there any configuration/step, I need to perform to resolve this issue?
Try to update PYSPARK_PYTHON and PYSPARK_DRIVER_PYTHON environment variables to the correct Python 3 distribution path
I have spark installed. And, I can go into the bin folder within my spark version, and run ./spark-shell and it runs correctly.
But, for some reason, I am unable to launch pyspark and any of the submodules.
So, I go into bin and launch ./pyspark and it tells me that my path is incorrect.
The current path I have for PYSPARK_PYTHON is the same as where I'm running the pyspark executable script from.
What is the correct path for PYSPARK_PYTHON? Shouldn't it be the path that leads to the executable script called pyspark in the bin folder of the spark version?
That's the path that I have now, but it tells me env: <full PYSPARK_PYTHON path> no such file or directory. Thanks.
What is the correct path for PYSPARK_PYTHON? Shouldn't it be the path that leads to the executable script called pyspark in the bin folder of the spark version?
No, it shouldn't. It should point to a Python executable you want to use with Spark (for example output from which python. If you don't want to use custom interpreter just ignore it. Spark will use the first Python interpreter available on your system PATH.
I am installing Apache Spark on linux. I already have Java, Scala and Spark downloaded and they are all in the Downloads folder inside the Home folder with the path /home/alex/Downloads/X where X=scala, java, spark, literally that's what the folders are called.
I got scala to work but when I try to run spark by typing ./bin/spark-shell it says:
/home/alex/Downloads/spark/bin/saprk-class: line 100: /usr/bin/java/bin/java: Not a directory
I have already included the file path by editing the bashrc with sudo gedit ~/.bashrc:
# JAVA
export JAVA_HOME=/home/alex/Downloads/java
export PATH=$PATH:$JAVA_HOME/bin
# scala
export SCALA_HOME=/home/alex/Downloads/scala
export PATH=$PATH:$SCALA_HOME/bin
# spark
export SPARK_HOME=/home/alex/Downloads/spark
export PATH=$PATH:$SPARK_HOME/bin
When I try to type sbt/sbt package in the spark folder it say no such file or directory is found also. What should I do from here?
It seems you have a few issues, namely your JAVA_HOME is not pointed to a directory with java, when you are running sbt in spark you should run ./sbt/sbt (or in new versions ./build/sbt). While you can download Java & Scala by hand, you may find that your system packages are sufficient (make sure to get jdk 7 or later).
Furthermore, after using system packages as Holden points out, in Linux you may use the command whereis to make sure of the right paths.
Finally, the following link may prove useful:
http://www.tutorialspoint.com/apache_spark/apache_spark_installation.htm
Hope this helps.
Note: It looks like there may be a configuration issue, misspelling, of the directory name
/home/alex/Downloads/spark/bin/saprk-class: line 100: /usr/bin/java/bin/java: Not a directory
saprk-class
That could be a configuration issue only, but it's worth a look if it is called /spark-class elsewhere to see if it's causing related issues.
I was trying to run spark-submit and I get
"Failed to find Spark assembly JAR.
You need to build Spark before running this program."
When I try to run spark-shell I get the same error.
What I have to do in this situation.
On Windows, I found that if it is installed in a directory that has a space in the path (C:\Program Files\Spark) the installation will fail. Move it to the root or another directory with no spaces.
Your Spark package doesn't include compiled Spark code. That's why you got the error message from these scripts spark-submit and spark-shell.
You have to download one of pre-built version in "Choose a package type" section from the Spark download page.
Try running mvn -DskipTests clean package first to build Spark.
If your spark binaries are in a folder where the name of the folder has spaces (for example, "Program Files (x86)"), it didn't work. I changed it to "Program_Files", then the spark_shell command works in cmd.
In my case, I install spark by pip3 install pyspark on macOS system, and the error caused by incorrect SPARK_HOME variable. It works when I run command like below:
PYSPARK_PYTHON=python3 SPARK_HOME=/usr/local/lib/python3.7/site-packages/pyspark python3 wordcount.py a.txt
Go to SPARK_HOME. Note that your SPARK_HOME variable should not include /bin at the end. Mention it when you're when you're adding it to path like this: export PATH=$SPARK_HOME/bin:$PATH
Run export MAVEN_OPTS="-Xmx2g -XX:ReservedCodeCacheSize=1g" to allot more memory to maven.
Run ./build/mvn -DskipTests clean package and be patient. It took my system 1 hour and 17 minutes to finish this.
Run ./dev/make-distribution.sh --name custom-spark --pip. This is just for python/pyspark. You can add more flags for Hive, Kubernetes, etc.
Running pyspark or spark-shell will now start pyspark and spark respectively.
If you have downloaded binary and getting this exception
Then please check your Spark_home path may contain spaces like "apache spark"/bin
Just remove spaces will works.
Just to add to #jurban1997 answer.
If you are running windows then make sure that SPARK_HOME and SCALA_HOME environment variables are setup right. SPARK_HOME should be pointing to {SPARK_HOME}\bin\spark-shell.cmd
For Windows machine with the pre-build version as of today (21.01.2022):
In order to verify all the edge cases you may have and avoid tedious guesswork about what exactly is not configred properly:
Find spark-class2.cmd and open it in with a text editor
Inspect the arguments of commands staring with call or if exists by typing the arguments in Command Prompt like this:
Open Command Prompt. (For PowerShell you need to print the var another way)
Copy-paste %SPARK_HOME%\bin\ as is and press enter.
If you see something like bin\bin in the path displayed now then you have appended /bin in your environment variable %SPARK_HOME%.
Now you have to add the path to the spark/bin to your PATH variable or it will not find spark-submit command
Try out and correct every path variable that the script in this file uses and and you should be good to go.
After that enter spark-submit ... you may now encounter the missing hadoop winutils.exe for which problem you can go get the tool and paste it where the spark-submit.cmd is located
Spark Installation:
For Window machine:
Download spark-2.1.1-bin-hadoop2.7.tgz from this site https://spark.apache.org/downloads.html
Unzip and Paste your spark folder in C:\ drive and set environment variable.
If you don’t have Hadoop,
you need to create Hadoop folder and also create Bin folder in it and then copy and paste winutils.exe file in it.
download winutils file from [https://codeload.github.com/gvreddy1210/64bit/zip/master][1]
and paste winutils.exe file in Hadoop\bin folder and set environment variable for c:\hadoop\bin;
create temp\hive folder in C:\ drive and give the full permission to this folder like:
C:\Windows\system32>C:\hadoop\bin\winutils.exe chmod 777 /tmp/hive
open command prompt first run C:\hadoop\bin> winutils.exe and then navigate to C:\spark\bin>
run spark-shell
