> According to the contract of {{UserGroupInformation.doAs()}} the only
> required operations within the {{doAs()}} block are the
> creation of a {{JobClient}} or getting a {{FileSystem}} .
> The {{DistributedCache.add(File/Archive)ToClasspath()}} methods create a
> {{FileSystem}} instance outside of the {{doAs()}} block,
> this {{FileSystem}} instance is not in the scope of the proxy user but of the
> superuser and permissions may make the method
> fail.
> One option is to overload the methods above to receive a filesystem.
> Another option is to do obtain the {{FileSystem}} within a {{doAs()}} block,
> for this it would be required to have the proxy
> user set in the passed configuration.
> The second option seems nicer, but I don't know if the proxy user is as a
> property in the jobconf.
