> ParquetFileReader throws a runtime exception when a file contains only

> Project: Parquet
> Issue Type: Bug
> Components: parquet-mr
> Affects Versions: 1.12.1
> Reporter: chris stockton
> Assignee: Gang Wu
> Priority: Minor
>
> Google BigQuery has an option to export table data to Parquet-formatted
> files, but some of these files are written with header data only. When this
> happens and these files are opened with the ParquetFileReader, an exception
> is thrown:
> {{RuntimeException("Illegal row group of 0 rows");}}
> It seems like the ParquetFileReader should not throw an exception when it
> encounters such a file.
