Resolution: Fixed
> Unfavorable change on the S3 scratch path behavior
> --------------------------------------------------

> Key: IMPALA-10945
> URL: https://issues.apache.org/jira/browse/IMPALA-10945
> Project: IMPALA
> Issue Type: Bug
> Components: Backend
> Affects Versions: Impala 4.1.0
> Reporter: Yida Wu
> Assignee: Yida Wu
> Priority: Major
>
> IMPALA-10429 "Support Spill to HDFS" introduces a new behavior to S3 scratch
> path.
> It added a connection verification logic for the S3 path (for optimization),
> but the HdfsFsCache requires the path to have a directory behind, like
> "s3a://host/dir", otherwise it will throw an error.
> [https://github.com/apache/impala/blob/1a61a8025c87c37921a1bba4c49f754d8bd10bcc/be/src/runtime/tmp-file-mgr.cc#L333]
> The change brings a problem, that may require the user to have a different
> s3a scratch path. It would be good to be compatible with the path we support
> in the previous version.
