Subject Re: Setting user in yarn in 2.1.0
Date Wed, 11 Sep 2013 17:38:43 GMT

Depends on what 'running means'. For all purposes other than launching the user's container
process, yes, the user who submits the application is considered - for e.g. ACLs, Nodemanager
security etc. In non-secure case when using DefaultContainerExecutor, the container still
runs as the user running YARN. In secure case, it will run as the app-submitter.

Thanks,

has been removed and is now in the container token.  Does this mean the application will now
always run as the user who submits the application, or is there some other way to set the
user now?
