> When creating a {{ParquetReader}}, a "read support" object is required.
> https://github.com/apache/parquet-mr/blob/master/parquet-hadoop/src/main/java/org/apache/parquet/hadoop/ParquetReader.java#L325-L330
> However, when building from an {{InputFile}}, 'readSupport' is always 'null' 
> and therefore will never work.
> https://github.com/apache/parquet-mr/blob/master/parquet-hadoop/src/main/java/org/apache/parquet/hadoop/ParquetReader.java#L202
> Add the read support option just as is done with a {{Path}} object.
