Ryan Blue commented on PARQUET-623:
-----------------------------------
We should change `skip` to call `readBytes` and discard the result if there
isn't a better fix. Thanks for reporting this, [~oae]!
> DeltaByteArrayReader has incorrect skip behaviour

> Key: PARQUET-623
> URL: https://issues.apache.org/jira/browse/PARQUET-623
> Project: Parquet
> Issue Type: Bug
> Affects Versions: 1.8.1
> Reporter: Johannes Zillmann
>
> When reading delta encoded columns (v2 API) and skipping values the read
> fails (with differing exceptions). This is because the reader needs the last
> value but the skip logic is not managing this.
> A modified DeltaByteArrayReader which calls readBytes() on skip() does fix
> the reading. Not sure if there is a more efficient solution possible then
> simply invoking readBytes().
