> I discovered the problem when running unit test TestMRJobClient on Windows.
> The cause is indirect in this case. In the unit test, we try to launch a job
> and list its status. The job failed, and caused the list command get a result
> of 0, which triggered the unit test assert. From the log and debug, the job
> failed because we failed to create the Jar with classpath (see code around
> {{FileUtil.createJarWithClassPath}}) in {{ContainerLaunch}}. This is a
> Windows specific step right now; so the test still passes on Linux. This step
> failed because we passed in a relative path to {{FileContext.globStatus()}}
> in {{FileUtil.createJarWithClassPath}}. The relevant log looks like the
> following.

> I think this is a regression from HADOOP-9817. I modified some code and the
> unit test passed. (See the attached patch.) However, I think the impact is
> larger. I will add some unit tests to verify the behavior, and work on a more
> complete fix.
