Craig Welch commented on YARN-3626:
-----------------------------------

The checkstyle is insignificant, the rest is all good.

> On Windows localized resources are not moved to the front of the classpath

> In response to the mapreduce.job.user.classpath.first setting the classpath 
> is ordered differently so that localized resources will appear before system 
> classpath resources when tasks execute.  On Windows this does not work 
> because the localized resources are not linked into their final location when 
> the classpath jar is created.  To compensate for that localized jar resources 
> are added directly to the classpath generated for the jar rather than being 
> discovered from the localized directories.  Unfortunately, they are always 
> appended to the classpath, and so are never preferred over system resources.
