[jira] [Commented] (AURORA-1988) Report "[Errno 13] Permission
denied" when run hello world when follow latest doc
[ https://issues.apache.org/jira/browse/AURORA-1988?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16512884#comment-16512884 ]
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.
