> The query results are staged in stagingdir that is relative to the
> destination path <destination_dir>/<staging_dir>/
> during blobstorage optimzation HIVE-17620 final job is set to use stagingdir.
> HIVE-15215 mentioned the possibility of using scratch for staging when write
> to S3 but it was long time ago and no activity.
>
> This is to allow final job to use hive.exec.scratchdir as the interim jobs,
> with a configuration
> hive.use.scratchdir.for.staging
> This is useful for cross Filesystem, user can use local source filesystem
> instead of remote filesystem for the staging.
