Craig Welch commented on YARN-2803:
-----------------------------------
So, these tests pass with the revision directly before [YARN-2198] checkin, and
fail for it and subsequent revisions (having checked several, including current
trunk - although behavior seems to differ slightly from the checkin until now).
A couple of differences are notable, although which is responsible is not yet
clear. Post 2198 the classpath*jar ends up with a reference to itself, which
does not seem correct (although it may or may not be the cause). the
non-secure windows path also ends up with a reference to the classpath jar in
the nmPrivate directory instead of in the usercache area as it did before the
change.

> Key: YARN-2803
> URL: https://issues.apache.org/jira/browse/YARN-2803
> Project: Hadoop YARN
> Issue Type: Bug
> Components: nodemanager
> Reporter: Chris Nauroth
> Priority: Critical
>
> 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.
