ProtoParquet
URL: https://github.com/apache/parquet-mr/pull/411#issuecomment-374883095
@virtualluke it seems related: the issue seems to be that your file are
missing the LIST wrapper around repeated fields (the 3-levels lists), and
instead using the 2-levels repetition style.
The 2-levels style is what parquet-protobuf currently does and this PR's aim
is to allow it to use the 3-levels way, which is how the parquet specs define
lists and maps when writting parquet files.
The PR you linked to does the opposite: allowing to read files that have
been written with the 2-levels style.
