Renan DelValle commented on AURORA-1988: ---------------------------------------- [~ggeng1] This looks like the python script doesn't have the correct permissions to run on the mesos-agent on which the task is getting scheduled. In the example, the executor is run as the <role> part of the configuration. Therefore, this task is trying to run under the user www-data. If the python script being placed in the box by this task doesn't have the right permissions, user www-data will not be able to execute it. > Report "[Errno 13] Permission denied" when run hello world when follow latest > doc > ---------------------------------------------------------------------------------- > > Key: AURORA-1988 > URL: https://issues.apache.org/jira/browse/AURORA-1988 > Project: Aurora > Issue Type: Bug > Components: Executor > Affects Versions: 0.20.0 > Environment: Mesos Version: 1.6.0 > Aurora Version: 0.20.0 > Aurora RPM: > aurora-scheduler-0.20.0-1.el7.centos.aurora.x86_64.rpm > aurora-executor-0.20.0-1.el7.centos.aurora.x86_64.rpm > Reporter: Geng Gang > Priority: Blocker > Labels: beginner > Attachments: screen1.jpg > > > Hi > I am new user for aurora.
