Description

When encryption is on, can't access ColumnChunkMetaData from the RowGroupMetaData.

For example, this code won't work with encryption on.

reader->metadata()
 ->RowGroup(0)
 ->ColumnChunk(0)
 ->num_values();

 

 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.
