Sean Owen resolved SPARK-5998.
------------------------------
Resolution: Won't Fix
Looks like this didn't go anywhere (and could be quite complex); it could be
reopened if needed.
> Make Spark Streaming checkpoint version compatible
> --------------------------------------------------
>
> Key: SPARK-5998
> URL: https://issues.apache.org/jira/browse/SPARK-5998
> Project: Spark
> Issue Type: Improvement
> Components: Streaming
> Affects Versions: 1.3.0
> Reporter: Saisai Shao
>
> Currently Spark Streaming's checkpointing(serialization) mechanism is version
> mutable, if the code is updated or any changes happened. The old
> checkpointing files cannot be read again. To keep the long-running and
> upgradability of streaming App, making the checkpointing mechanism version
> compatible is meaning.
> Here creating a JIRA as stub of this issue, I'm currently working on this, a
> design doc will be posted later.
