> 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
