> When encryption is on, can't access ColumnChunkMetaData from the
> RowGroupMetaData.
> For example, this code won't work with encryption on.
> {code:c++}
> reader->metadata()
> ->RowGroup(0)
> ->ColumnChunk(0)
> ->num_values();
> {code}
>
> One implication is that the Parquet Arrow API doesn't work with encryption
> on.
> Tests for the Parquet Arrow API (with encryption) are soon to follow in a
> separate PR.
