-----------------------------------
Assignee: Sital Kedia
> Remove all shuffle files on a host in case of slave lost of fetch failure
> -------------------------------------------------------------------------
>
> Key: SPARK-19753
> URL: https://issues.apache.org/jira/browse/SPARK-19753
> Project: Spark
> Issue Type: Bug
> Components: Scheduler
> Affects Versions: 2.0.1
> Reporter: Sital Kedia
> Assignee: Sital Kedia
> Fix For: 2.3.0
>
>
> Currently, when we detect fetch failure, we only remove the shuffle files
> produced by the executor, while the host itself might be down and all the
> shuffle files are not accessible. In case we are running multiple executors
> on a host, any host going down currently results in multiple fetch failures
> and multiple retries of the stage, which is very inefficient. If we remove
> all the shuffle files on that host, on first fetch failure, we can rerun all
> the tasks on that host in a single stage retry.
