Falcon clusters with multiple users

avatar
Master Guru

I want to schedule falcon jobs with different service accounts. user1 with process1 and user2 with process2. But they should use the same cluster.

However this does not work because falcon creates a folder "process" under the staging directory with user1 and a subfolder process1. When I try to submit a process with user2 it fails because it cannot create the folder process2 under the same folder.

Is this actually the supposed behavior? Do I have to create one cluster each for every user who wants to submit falcon jobs pointing to different staging folders? That sounds pretty inconvenient

I changed the staging/falcon folder to belong to a group of both users. And changed its access rights to 775, this seems to work until now.

Benjamin Leonhardi: You need to provide correct permissions to staging and working directories. Please use falcon tutorial for reference.

I did. The subfolder falcon creates however is created with the user I created the first process with. So a second user does not work anymore.

Most likely was this. Sorry for not accepting for so long but when I changed the <falconfolder>/staging/falcon folder manually it all worked and I forgot about it Thanks a lot.
