> If a folder is given as an input path to GiraphFileInputFormat, the default 
> hidden file filter is not applied to the files in the folder. That is, hidden 
> files (e.g. files preceded by underscores) that would not normally be handled 
> if targeted directly are unexpectedly being passed as input if the parent 
> folder is targeted instead.
> I would expect that when a folder is specified as input, only *non-hidden* 
> files in that folder will be processed. This is consistent with the base 
> hadoop FileInputFormat.
