Feng Tian commented on ARROW-8138:
----------------------------------
I attached a quick repro – bug.parquet is a data file with multiple row groups,
each row is a int, float pair. bug.cpp should repro.
As a side notes – I generally follow the cpp examples, but seems none of the
parquet examples cover the case of multiple rowgroups.
> parquet::arrow::FileReader cannot read multiple RowGroup
