Eric Yang commented on YARN-7816:
---------------------------------
ServiceClient is performed in doAs call, using System.getProperty("user.name")
might return YARN service user instead of end user username. It would be good
to change the retrieval of username by calling:
UserGroupInformation.getCurrentUser();
> YARN Service - Two different users are unable to launch a service of the same
> name

> Now that YARN-7605 is committed, I am able to create a service in an
> unsecured cluster from cmd line as the logged in user. However after creating
> an app of name "myapp" say as user A, and then I login as a different user
> user B, I am unable to create a service of the exact same name ("myapp" in
> this case). This feature should be supported in a multi-user setup.
