> 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}
