Hyukjin Kwon resolved SPARK-23322.
----------------------------------
Resolution: Incomplete
> Launcher handles can miss application updates if application finishes too
> quickly
> ---------------------------------------------------------------------------------
>
> Key: SPARK-23322
> URL: https://issues.apache.org/jira/browse/SPARK-23322
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 2.3.0
> Reporter: Marcelo Masiero Vanzin
> Priority: Minor
> Labels: bulk-closed
>
> This is the underlying issue in SPARK-23020, which was worked around in our
> tests, but still exist in the code.
> If a child application finishes too quickly, the launcher code may clean up
> the handle's state before the connection from the child has been
> acknowledged. This means than the application handle will have a final state
> LOST instead of whatever final state the application sent.
> This doesn't seem to affect child processes as much as the new in-process
> launch mode, and it requires the child application to finish very quickly,
> which should be rare for the kind of use case the launcher library covers.
