> 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 passed 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.
