> -----------------------------------------------
>
> Key: SPARK-4555
> URL: https://issues.apache.org/jira/browse/SPARK-4555
> Project: Spark
> Issue Type: Improvement
> Components: Spark Core
> Reporter: Josh Rosen
> Priority: Major
> Labels: bulk-closed

> The web UI / event listener's JsonProtocol is designed to be backwards- and forwards-compatible: newer versions of Spark should be able to consume event logs written by older versions and vice-versa.
> We currently have backwards-compatibility tests for the "newer version reads older log" case; this JIRA tracks progress for adding the opposite forwards-compatibility tests.
> This type of test could be non-trivial to write, since I think we'd need to actually run a script against multiple compiled Spark releases, so this test might need to sit outside of Spark Core itself as part of an integration testing suite.
