ParquetReader directory read using InputFile

[asfimport]

Using Hadoop Path, users can read from directories (excluding hidden files) using a single ParquetReader. This is not yet possible using the InputFile API. To resolve this, a generic way should be added for directories to be read, consistent with the behaviour of the read API when using a Hadoop Path.
