> Key: IMPALA-13677
> URL: https://issues.apache.org/jira/browse/IMPALA-13677
> Project: IMPALA
> Issue Type: Improvement
> Components: Backend
> Reporter: Yida Wu
> Assignee: Yida Wu
> Priority: Critical
> Fix For: Impala 4.5.0
>
>
> Currently, when an executor spills data to a remote storage, scratch files
> would remain in the remote storage if the executor exits abnormally or is
> terminated after the graceful shutdown deadline.
> Immediate removal may be challenging, and no concrete solution is currently
> available. However, to clear leftover files on startup is possible.
