Chris Nauroth commented on YARN-2803:
-------------------------------------
Thanks again, Craig. I re-verified that the tests pass in my environment with
this version of the patch. I agree with the argument to retain the current
behavior of secure mode (such as it is).
Sorry to nitpick, but it looks like some lines are indented by 1 space instead
of 2. Would you mind fixing that? I'll be +1 after that.

> Key: YARN-2803
> URL: https://issues.apache.org/jira/browse/YARN-2803
> Project: Hadoop YARN
> Issue Type: Bug
> Components: nodemanager
> Reporter: Chris Nauroth
> Assignee: Craig Welch
> Priority: Critical
> Attachments: YARN-2803.0.patch, YARN-2803.1.patch
>
>
> This problem is visible by running {{TestMRJobs#testDistributedCache}} or
> {{TestUberAM#testDistributedCache}} on Windows. Both tests fail. Running
> git bisect, I traced it to the YARN-2198 patch to remove the need to run
> NodeManager as a privileged account. The tests started failing when that
> patch was committed.
