> Key: PARQUET-1747
> URL: https://issues.apache.org/jira/browse/PARQUET-1747
> Project: Parquet
> Issue Type: Bug
> Components: parquet-cpp
> Reporter: Gal Lushi

> 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.
