> change "-tokenCacheFile" option to support non-local FS URIs.
> The current code in GenericOptionsParser only support local FS URIs, It will be better
to support non-local FS URIs. 
> {code}
>     FileSystem localFs = FileSystem.getLocal(conf);
>       Path p = localFs.makeQualified(new Path(fileName));
>       if (!localFs.exists(p)) {
>           throw new FileNotFoundException("File "+fileName+" does not exist.");
>       }
> {code}
> We can change above code to
> {code}
>     FileSystem localFs = FileSystem.getLocal(conf);
>       Path p = localFs.makeQualified(new Path(fileName));
>       if (!p.getFileSystem(conf).exists(p)) {
>           throw new FileNotFoundException("File "+fileName+" does not exist.");
>       }
> {code}
> This issue will depend on MAPREDUCE-6086.
