> Impala truncates insert-only parquet tables by creating a base directory
> containing a completely empty file.
> Hive throws an exception upon reading when it looks for metadata:
> {code:java}
> Error: java.io.IOException: java.lang.RuntimeException: <file> is not a
> Parquet file (too small length: 0) (state=,code=0){code}
> We can introduce a check for an empty file before Hive tries to read the
> metadata.
