Using TDSet in ProofLite

[Manoj Kumar Jha]

Hello,
I generated an input root file from $ROOTSYS/test/Event executable.
I used MakeSelector utility to generate the analysis code so that it can
be run using PROOF. I am using TDSet as input file collection.
Somehow, my code is crashing while reading entries from the input file.

How to reproduce it ?

Could you please look into it ?

Hi Manoj,

I am not able to reproduce your problem using the AFS installation of ROOT 5.34/18. See attachment.
Is there a way I can try in your exact environment?

Hi Gerri,
Thanks for your help. I am using root from CMS software release.
Please see the attached file for how to reproduce the error. Is it
possible to use root installation in AFS from CVMFS area ?

Regards.
Manoj
