> Avoid caching the removed decommissioned executors in TaskSchedulerImpl
> -----------------------------------------------------------------------
>
> Key: SPARK-32736
> URL: https://issues.apache.org/jira/browse/SPARK-32736
> Project: Spark
> Issue Type: Improvement
> Components: Spark Core
> Affects Versions: 3.1.0
> Reporter: wuyi
> Priority: Major
>
> We can save the host directly in the ExecutorDecommissionState. Therefore,
> when the executor lost, we could unregister the shuffle map status on the
> host. Thus, we don't need to hold the cache to wait for FetchFailureException
> to do the unregister.
