Ram Venkatesh created YARN-4842:
-----------------------------------
Summary: yarn logs command should not require the appOwner argument
Key: YARN-4842
URL: https://issues.apache.org/jira/browse/YARN-4842
Project: Hadoop YARN
Issue Type: Bug
Reporter: Ram Venkatesh
The yarn logs command is among the most common ways to troubleshoot yarn app
failures, especially by an admin.
Currently if you run the command as a user different from the job owner, the
command will fail with a subtle message that it could not find the app under
the running user's name. This can be confusing especially to new admins.
We can figure out the job owner from the app report returned by the RM or the
AHS, or, by looking for the app directory using a glob pattern, so in most
cases this error can be avoided.
Question - are there scenarios where users will still need to specify the
-appOwner option?
