Description

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.

Research direction

Start by comparing the existing Hadoop Path directory-reading behavior with the InputFile API described in the issue. Define how a generic directory read should work, including excluding hidden files and preserving single-reader behavior, then verify the result against the existing read API behavior.
