[jira] [Created] (PARQUET-1580) Implement page-level checksum validation

Boudewijn Braams created PARQUET-1580:
-----------------------------------------

             Summary: Implement page-level checksum validation
                 Key: PARQUET-1580
                 URL: https://issues.apache.org/jira/browse/PARQUET-1580
             Project: Parquet
          Issue Type: Improvement
          Components: parquet-mr
            Reporter: Boudewijn Braams
            Assignee: Boudewijn Braams


Now that the specification with respect to page level checksums has been clarified (see https://jira.apache.org/jira/browse/PARQUET-1539), we can actually implement it. What needs to be done:
* Implement calculating and writing checksums on write path
* Implement checksum validation on read path
* Make writing out checksums and validation on reads optional (default off)
* Implement tests
