[~mwish] for the record. Perhaps you would be interested in doing this, if you
can do some Java.

> Key: PARQUET-1629
> URL: https://issues.apache.org/jira/browse/PARQUET-1629
> Project: Parquet
> Issue Type: Improvement
> Components: parquet-mr
> Reporter: Boudewijn Braams
> Priority: Major
>
> In https://jira.apache.org/jira/browse/PARQUET-1580 (Github PR:
> https://github.com/apache/parquet-mr/pull/647) we implemented page level CRC
> checksum verification for DataPageV1. As a follow up, we should add support
> for DataPageV2 that follows the spec (see see
> https://jira.apache.org/jira/browse/PARQUET-1539).
> What needs to be done:
> * Add writing out checksums for DataPageV2
> * Add checksum verification for DataPageV2
> * Create new test suite
> * Create new benchmarks
