@etejedor @vbrian this is quick fix
pyrdf_fix.sh script withsource /cvmfs/sft.cern.ch/lcg/views/dev3python3/Wed/x86_64-slc6-gcc8-opt/setup.sh
$CERNBOX_HOME/pyrdf_fix.sh
You have thus time until this Wednesday until the broken package is fixed. @etejedor can you help us raise issue to Bleeding Edge maintainers?
Hi,
Do you have more information about the error? It is hard to tell what is going on.
When you say there is a broken package, you mean PyRDF? How do you know it is PyRDF? No new version should have been published on bleeding edge for PyRDF, no update has happened in the past few weeks.
@etejedor I don’t know what is broken exactly
Brian has Caused by: java.io.EOFException which is essentially meaning some stage in the middle exploded and did not return result, I get some crazy segmentation faults from ROOT
*** Break *** segmentation violation

I can give to some developer detailed logs of what happened if needed. We can maybe take this offline.
Dear Piotr,
If you don’t mind, and if possible, I would be glad to be in some mailing loop. Even if I won’t help anyone, but just by curiosity 
@vbrian did the quickfix with additional source unblock you? Probably the one from Thursday/Friday will also work 
Yes, as soon as we know the root-cause probably we will post here.
@pmrowczy I tried but no, it seems that it does not override the environment as I would have expected
i.e. same error and
echo $LCG_VIEW
/cvmfs/sft.cern.ch/lcg/views/dev3python3/latest/x86_64-centos7-gcc8-opt
@vbrian @etejedor ok, I made it work by changing to this in $CERNBOX_HOME/pyrdf_fix.sh and used any PyRDF Notebook:

I have no idea what is wrong with ROOT in dev3python3/Mon
Hi Brian,
We are deploying a new container image for the k8s Spark clusters that should solve the issue. We’ll let you know when you can try again.
Cheers,
Enric
Dear Enric,
Thanks a lot, good news ! At least Piotr’s workaround is working fine (and I have no urgent time constraint right now…). By curiosity, have you spotted the issue ?
Cheers,
Brian
Hi Brian,
The crash was due to a newly introduced dependency of ROOT with glibc-headers, which was not installed in the k8s image.
Cheers,
Enric
Dear @vbrian
The new image (swan:v2) for spark executors with glibc-headers is deployed now. Please can you give it a try without the workaround and my recreating your spark session. Thank you
regards,
Prasanth
Dear Prasanth, Dear Piotr, Dear Enric, Dear everyone,
It seems to work ! Great job 
Thanks a lot for your reactivity and help on that
Best regards,
Brian
