I follow the step on page 21-26 from the book Data Engineering with Python to set up a data flow.
GenerateFlowFile Setting
PutFile Setting
Seems like some of the steps are missing. I can't find any folder in the /opt folder or any file in /opt/nifioutput. This is running on ubuntu 22.04
PutFile processor is stopped. Make on it right click and choose "Start". If you observe any popup errors - read carefully, they may guide you to the missing configuration.

I've downloaded Apache nifi 1.17.0 and tried to start it by bin/run0nifi.bat, but it didn't work. When I click on it window open and disappear in the same time.
I'm working on windows 11 pro
What should i do?
I tried to start it by console and tried to start 1.19.1 and unfortunately it didn't help
I'm a beginner so I might not have done some obvious things
Thx for help)
You need to do two things first of all:
you need to make sure that you have installed JAVA on your machine and set the PATH for the JDK in the Environment Variables (JAVA_HOME).
If JAVA is configured correctly you need to open CMD and go within the NiFi Folder. From there, you should execute the run-nifi.bat manually and see if anythings gets written in the CMD window.
Besides that, you can go within the logs folder and see if any logs are being generated. Most likely you will find something in the nifi-app.log.
My problem described in the title.
But in addition, I have set in the next directiory C:\OpenServer\modules\yarn Yarn and I don't know what to do next.
I hope for your help because I didn't find anything on Google or in the net.
I found it! Yeh!
We need to change in settings on the 'server' tab one option and create a file that will say which programs OpenServer must get and prefetch.
I am new to apache NIFI. I was kind of wondering where is the save button. I tried a sample from a tutorial that I saw on youtube. I would like to save all the processors that I created for future reference. I don't see any save button. Is is possible to save my work open later.? Or open in another machine.?
Please Help.
Apache NiFi automatically saves your flow for you. The flow configuration file is stored in ./conf/flow.xml.gz by default. NiFi also maintains an archive of previous versions in ./conf/archive. See the Core Properties settings for changing these settings. It is possible to backup and restore the flow configuration through these files.
Apache NiFi also has a Templates feature that makes it easy to save a selection from your flow, export it from the UI, and share it with other NiFi installations. Templates may be a closer approximation of a "save" button.
The Apache Nifi Registry is another option. You can version processor groups, commit changes to the registry, revert back, add comments, etc. I see it as similar to version control such as Git. It's helpful in collaborative settings as well as promoting changes from development to production.
I want to install InfluxDB on Windows for Jmeter. Can any one guide me how it can be done. Because I cannot find any specific link to get a Windows version of InfluxDB. Is Windows supported by InfluxDB ?
Thankyou.
Yes, InfluxDB runs fine on windows as well.
You can get the windows installable here.
Additional Info:
If you are unable to locate the config file, You can make influxdb display the default config.
For ex: influxd.exe config
This command displays all the default values. So create a config file with default values and modify as you need.
Then restart influxdb with below command to make the changes effective.
influxd.exe -config /path/to/config/file
Take a look at Docker and look at the influxDB docker file. You can easy run influxDB on your localhost
If you need a 32bit version, you will need to compile it yourself. This is certainly possible but you will also need golang.
I've not done it myself so I can't be sure of the exact instructions. However there are instructions from the middle of 2015 here: http://mickesommar.com/post/Compile_influxdb_for_windows/
Also the InfluxDB github source contains some example 32bit Docker files (though not for Windows).
I'm trying to install/configure FishEye as per the instructions on Atlassian's website, but either the web server for the install doesn't start properly (and I see multiple exception message in the command window), or I get a 503 Response code when I try to access the installation link.
How can I get past this?
The installation instructions currently aren't clear, especially on a Windows environment.
Here's what you need to do (in my case on a Windows system).
Extract the fisheye archive to the directory where you're intending to run Fisheye from. (on my system, I made this <drive>:\Atlassian\FishEye).
Create a directory for your data. (I made this <drive>:\Application Data\FishEye)
Create an environment variable (Window System Variable) named 'FISHEYE_INST' and set it to the path you created in Step 2. ('INST' in this case means instance and not installation folder.
Copy the 'config.xml' file from <extracted_archive> to your FISHEYE_INST folder.
Open a command prompt and run the <extracted archive>\bin\run.bat file. (ie :\Atlassian\FishEye\bin\run.bat).
The online documentation is a little misleading at this point. They indicate that you run 'start.bat', which won't work (or at least, it wouldn't work for me...)
Open a browser and point it to 'http://localhost:8060'.
Following the steps above let me get FishEye up and running without any further issues.
