Apache Spark reassigned SPARK-20664:
------------------------------------
Assignee: (was: Apache Spark)
> Remove stale applications from SHS listing
> ------------------------------------------
>
> Key: SPARK-20664
> URL: https://issues.apache.org/jira/browse/SPARK-20664
> Project: Spark
> Issue Type: Sub-task
> Components: Spark Core
> Affects Versions: 2.3.0
> Reporter: Marcelo Vanzin
>
> See spec in parent issue (SPARK-18085) for more details.
> This task is actually not explicit in the spec, and it's also an issue with
> the current SHS. But having the SHS persist listing data makes it worse.
> Basically, the SHS currently does not detect when files are deleted from the
> event log directory manually; so those applications are still listed, and
> trying to see their UI will either show the UI (if it's loaded) or an error
> (if it's not).
> With the new SHS, that also means that data is leaked in the disk stores used
> to persist listing and UI data, making the problem worse.
