Hyukjin Kwon resolved SPARK-22963.
----------------------------------
Resolution: Incomplete
> Make failure recovery global and automatic for continuous processing.
> ---------------------------------------------------------------------
>
> Key: SPARK-22963
> URL: https://issues.apache.org/jira/browse/SPARK-22963
> Project: Spark
> Issue Type: Improvement
> Components: Structured Streaming
> Affects Versions: 2.3.0
> Reporter: Jose Torres
> Priority: Major
> Labels: bulk-closed
>
> Spark native task restarts don't work well for continuous processing. They
> will process all data from the task's original start offset - even data which
> has already been committed. This is not semantically incorrect under at least
> once semantics, but it's awkward and bad.
> Fortunately, they're also not necessary; the central coordinator can restart
> every task from the checkpointed offsets without losing much. So we should
> make that happen automatically on task failures instead.
