Having a bit of a strange problem with Mesos 0.22, running Spark 1.4.0, on Docker 1.6 slaves. Part of my Spark program calls on a script that accesses a GPU. I am able to run this script:
1. As Bash 2. Via Marathon 3. As part of a Spark program running as a standalone master However, when I try to run the same Spark program with Mesos as master, i.e., spark-submit --master mesos://\`cat /etc/mesos/zk\` --deploy-mode client..., I am not able to access dri devices, e.g., mfx init: /dev/dri/renderD128 fd open failed. What seems to be happening is that the group membership of the default user, in this case "ubuntu" is modified by Mesos, i.e., whereas under cases 1-3, above, I get: $ id uid=1000(ubuntu) gid=1000(ubuntu) groups=1000(ubuntu),4(adm),20(dialout),24(cdrom),25(floppy),27(sudo),29(audio),30(dip),44(video),46(plugdev),102(netdev),999(docker) In case of Mesos, I get: uid=1000(ubuntu) gid=1000(ubuntu) groups=1000(ubuntu),0(root) I am wondering if there are configuration parameters that can be passed to Mesos to prevent it from modifying user groups?
