Uncommenting python config in nifi.properties makes Nifi crash on startup.

[#1]

Hi.

I'm trying to use Python extensions with Nifi.

I've uncommented the line   nifi.python.command=python3   in nifi.properties but Nifi always crash when I try to run it.

When I re-comment the line, Nifi starts and works fine.

I've read this thread  https://community.cloudera.com/t5/Support-Questions/Nifi-2-0-0-M1-Installation-error-with-python/m-p...

and tried to follow the instructions in the solutions.

It still crashes.

I'm posting here because the problem is on Windows instead of Linux.

Thanks for your help!

OS	Windows 10 home edition
Nifi version	nifi-2.0.0-M2
Java installed version	21.0.2
Python installed version	3.11.8

nifi.properties

In   nifi.properties   I changed the line from   nifi.python.command=python3   to   nifi.python.command=python

Venv

I made sure the python venv package is installed by issuing this command   python -m venv

which gave this message

usage: venv [-h] [--system-site-packages] [--symlinks | --copies] [--clear] [--upgrade] [--without-pip] [--prompt PROMPT] [--upgrade-deps] ENV_DIR [ENV_DIR ...]

venv: error: the following arguments are required: ENV_DIR

showing that venv is installed

Java version

java --version

java 21.0.2 2024-01-16 LTS

Java(TM) SE Runtime Environment (build 21.0.2+13-LTS-58)

Java HotSpot(TM) 64-Bit Server VM (build 21.0.2+13-LTS-58, mixed mode, sharing)

Python version

python --version

Python 3.11.8

The java_home env variable

echo %java_home%

C:\Program Files\Java\jdk-21

python3

python3 does not work. There is no python3 command in the python installation folder. Only a .dll :

dir C:\Users\ASUS\AppData\Local\Programs\Python\Python311

<DIR> DLLs

<DIR> Doc

<DIR> include

<DIR> Lib

<DIR> libs

      LICENSE.txt

      NEWS.txt

      python.exe

      python3.dll

      python311.dll

      pythonw.exe

<DIR> Scripts

<DIR> tcl

<DIR> Tools

      vcruntime140.dll

      vcruntime140_1.dll

That's why I changed the line to   nifi.python.command=python   in nifi.properties

The work/python folder

Nothing was copied to the ./work/python/controller/bin folder. The folder is not even existing.

Hi @coelacanth ,

Its me again from the first post you read that helped you resolve the first issue 🙂 All I can say is welcome to the club. the good news for you is i already went through this process and got it working - on windows as well- so hopefully I can get you going as well and save you some headache and time. Basically Enabling the Python Extension out of the box on windows is not going to work and Im not sure if there was any testing done on windows before releasing this feature.  First, you are right about python3 vs python as there is no such file under python windows and it should be changed to python. The second problem is the bin folder as it doesnt get created when the python venv  gets deployed to the controller folder first when you enable this feature, or when you add any new python extension processor. It seems under windows it creates a folder called Script where it stores all the python commands (.exe), so all you have to do is basically create the bin folder uder

.\work\python\controller

then copy whatever is under the "Script" folder to it and restart nifi and hopefully it will work. You only have to do that once for the controller folder but when you add new python processor and the vevn gets created for it under

\work\python\extensions\[Custom Processor]\2.0.0-SNAPSHOT\

You have to do the same thing of creating the bin folder and copying whatever in the Script folder to get it working. Actually the steps I do are the following:

1- Create the Custom processor

2- Copy the custom processor to the python extension folder .\python\extensions

3- Run Nifi the first time to create the Venv for the new processor under

.\work\python\extensions\[Custom Processor]\2.0.0-SNAPSHOT\

4- once the venv folder is created, turn nifi OFF because the custom processor is not going to load correctly and its going to keep saying "installing third party components...".

5- Create the bin folder and copy whatever in the script folder to it

\work\python\extensions\[Custom Processor]\2.0.0-SNAPSHOT\bin

6- Run nifi again. If everything is setup correctly with the processor and there is no compiler error , it will take few mins to download the dependencies ( depends ho many you have) and then it should work.

The Nifi development community needs to fix this bug either internally looking for the script folder aside from the bin folder, or make that configurable in the nifi.properties.

Note about out of the box python extensions: You might have problem getting the dependencies downloaded correctly for the ParseDocument extension. You might need to download those dependencies manually to get it to  work and here is another trick for you: if you happen to download those dependencies manually you need to create a file "dependency-download.complete"  with "True" value inside under the processor path 

\work\python\extensions\[Custom Processor]\2.0.0-SNAPSHOT\

to let nifi know that its finished downloading the dependencies and remove the error from the processor.

@pvillard, this is another issue that needs your attention. I mean to write an article about this but did not have the time.

Any way hopefully that is enough info to get you going. let me know if you have any other questions.

If you find this is helpful, please accept solution.

Thanks

@SAMSAL a huge thanks!
I only tried the bin solution on the work\python\controller and nifi no longer crashes.
First thing tomorrow I'll try it with a new processor.

Also thanks for the tips about dependencies 🙂

@SAMSAL 

I've created a new python processor following your instructions and it worked.

The in box processors work too.

So I confirm the "Windows bin" solution worked on my side too.

Again thank you for your help!

@coelacanth,

My pleasure! Im glad it worked . If you find a better way than having to manually create the bin folder then copy the files from the script folder to it and restarting nifi every time you add new python processor or create the bin folder, please let us know and share. Right now for every python processor I create I have to restart my nifi instance 2 times:

1- Deploy the processor to the canvas so that the venv is created.

2- After the venv is created to copy the files to the bin folder.

I know  its possible to create vevn manually under the work folder and get it setup without relying much on Nifi to do it but Im afraid that might interfere with the process and cause other problems.

@pvillard, @MattWho , @cotopaul  please if you know better workaround for this let us know.
