DSS Startup failed on MacOS 11 Big Sur

AndreyK

I've updated MacOS up to 11.0 and can't use DSS. Reinstall don't solve problem.

I get following message when DSS starting:

I've found workaround:

1. Reinstall DSS (may be it works without reinstall but I did it in my case)
2. You will get same error when DSS starting up. Close DSS.
3. open Terminal and run:

/Applications/DataScienceStudio.app/Contents/Resources/kit/installer.sh -d /Users/<your_user_name>/Library/DataScienceStudio/dss_home -y -u -n

Note: option -n force compatability check

Note: in all commands replace <your_user_name> with your own user name

4. Run following command when setup script finishes:

/Users/<your_user_name>/Library/DataScienceStudio/dss_home/bin/dss start

and wait some time before backend starts

5. Open your browser and open DSS page: http://localhost:11200/

Please note that with the most recent release (version 8.04) this issue has been resolved.

Download DSS version 8.04

CoreyS

Glad that helped! In the future you can try to modify the install-deps.sh script to prevent the “notSupported” function from being called after the OS version check is done. You can do this by editing /Applications/DataScienceStudio.app/Contents/Resources/kit/scripts/install/install-deps.sh and either remove or comment out lines 174 - 176:

if [ "$major" -ne 10 -o "$minor" -lt 12 ]; then
notSupported
fi

If you have an existing local DSS instance that was installed via the command line (i.e. you used the osx.tar.gz instead of the dmg file), then it will continue working when you start DSS. Probably you will need to modify install-deps.sh though if you’re looking to do a fresh “command line” install on Mac using the osx installer.

Thanks Corey, it worked perfectly.

@AndreyK

I'm wondering if you are running DSS on MacOS 11 running on Intel Chip Set OR apple Silicon M1.

Based on my research about Homebrew on Apple Silicon M1 Chip, my guess would be that you are running on Intel? However, it would be very cool if you told us you were running on Apple Silicon M1 under Rosetta 2.

LelandMont

Hi, Corey - I read the discussion above very carefully. I am trying to start DSS 8.04 on a MacBook Pro running Mac OS 11.1 Big Sur, and the error message I get is: Your last post says 8.04 fixes this, but apparently not. I also tried inputting the code you provided in the Terminal, but got this error message. I'm not really experienced at terminal, so maybe its just me. Any help you can offer would be great!

CoreyS

Hi @LelandMont
, this isn't actually related to compatibility. Depending on your security settings, OS X might prevent DSS from starting. Open System Preferences, go to “Security & Privacy” and authorize the application

More info can be found on our website: Install Dataiku on Mac and in our Documentation: Install on macOS

I hope this helps!

troyangrignon

Hi @CoreyS
, I'm on a Mac Mini running Mac OS 11.1 (20C69) Big Sur. I have attempted both of the proposed fixes here in this thread but the problem persists. Essentially the backend won't start. I did get it running one time, but it has never worked since.

I've deleted and reinstalled the entire DSS folder in the Library and the app, and all of those reinstalls have been from the 8.0.4 dmg file. I've rebooted the computer between installations. All to no avail.

Backend.log is showing:

Any thoughts? Seems like perhaps this is not solved completely in 8.0.4?

Thanks for your help. Let me know if I can grab any other log files for you.

CoreyS

Hi @troyangrignon
to confirm is your Mac Mani with the M1 chip? If it is, unfortunately at this time DSS installation on Apple M1 MacBooks is not supported. We currently do not have an ETA for a compatible release.

More information about M1 compatibility with DSS can be found on this thread:

I hope this helps and I look forward to your confirmation.

troyangrignon

It is not the M1 chip. It's the 3.2GHz 6-Core Intel Core i7.

As a work-around for now, I have installed VirtualBox and set it up in there using your .OVA but if you find out more information about running it natively that solves this, I'd love to hear about it.

Sergey

Hi @troyangrignon

'/Users/MyUserNameRedacted/Library/DataScienceStudio/dss_home/config/general-settings.json' does not exist

means there was either installation or some kind of permission issue. This file is basically "main" config file of DSS.

Can you please check/list the content of /Users/MyUserNameRedacted/Library/DataScienceStudio/dss_home/config/ directory (ls -lA)?

Can you please provide the install.log from /Users/<username>/Library/DataScienceStudio/dss_home/run directory for review?

troyangrignon

Sure, see attached. Keep in mind that I've deleted the entire DSS folder multiple times so this log only has a few of the installs in it.

Sergey

Thanks. I found several attempts to install DSS and some of them have failed but I am more concerned about this one:

/Applications/DataScienceStudio.app/Contents/Resources/kit/scripts/install/install-deps.sh: line 178: syntax error near unexpected token `fi'

It's not expected to see such error and look like you commented out wrong lines. More importantly, for DSS8.0.4 you don't need to comment out anything as we have added support for BigSur already. So please make sure you revert all the changes done to install-deps.sh (or any other files) script and run the installation once again. You might need to wipe out everything and start from scratch.

I have just checked and can confirm there are no issues installing DSS8.0.4 on macOS 11.1 (20C69):

troyangrignon

Thanks @Sergey

I definitely commented out some wrong lines on one of the passes (the directions in this post were slightly off I thought.)

I’m buried today but will re-attempt later.

I definitely deleted the whole DSS folder and app, then deleted trash (which would have removed any modifications I made to the install-deps.sh file) and then reinstalled from 8.0.4 DMG. As in…probably 5 times.

I’ll try again tonight or tomorrow when I have time and will let you know. Meanwhile my VM is running fine in VirtualBox.

Thanks

Troy

troyangrignon

@Sergey
I deleted the DSS app and the /Library/DataScienceStudio folder, emptied the trash and restarted and then reinstalled from a clean 8.0.4 .dmg file. Upon launch it failed. Once again it looks like some sort of Java failure. I did download Java Version 8, Update 281 (current recommended version for Mac OS X).

Install.log now shows:

I am facing a similar issue. I'm authorizing it, but nothing happening after it. Getting prompt as shown in attachment.

Hi @Vivek_Gupta
to confirm what happens when you click open anyway? Can you send a screenshot of what that error looks like?

Similarly, have you tried uninstalling and reinstalling DSS to see if you can reproduce this issue?

fho

Hi, thank you. This install page https://www.dataiku.com/de/produkt/erste-schritte/mac/ would still download Data Science Studio 8.0.0.dmg, which produces the install problem.
