Description

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.
