> When {{mkdirs(Path)}} is called against {{LocalFileSystem}}, the
> implementation in {{RawLocalFileSystem}} is called and the directory
> permission is determined by the umask. However, if it is under
> {{ViewFileSystem}}, the default implementation in {{FileSystem}} is called
> and this causes explicit {{chmod()}} to 0777.
> The {{mkdirs(Path)}} method needs to be overriden in
> - ViewFileSystem to avoid calling the default implementation
> - ChRootedFileSystem for proper resolution of viewfs mount table
> - FilterFileSystem to avoid calling the default implementation
> Only then the same method in the target ({{LocalFileSystem}} in this case)
> will be called. Hdfs does not suffer from the same flaw since it applies
> umask in all cases, regardless of what version of {{mkdirs()}} was called.
