Yi Zhang updated HIVE-26758:
----------------------------
Summary: Allow use scratchdir for staging final job (was: Allow use
scratchdir for staging)
> Allow use scratchdir for staging final job
> ------------------------------------------
>
> Key: HIVE-26758
> URL: https://issues.apache.org/jira/browse/HIVE-26758
> Project: Hive
> Issue Type: New Feature
> Components: Query Planning
> Affects Versions: 4.0.0-alpha-2
> Reporter: Yi Zhang
> Assignee: Yi Zhang
> Priority: Minor
> Labels: pull-request-available
> Time Spent: 10m
> Remaining Estimate: 0h
>
> The query results are staged in stagingdir that is relative to the
> destination path <destination_dir>/<staging_dir>/
> It used to be able to change hive.exec.stagingdir for a different location,
> but that is lost during blobstorage optimzation HIVE-17620.
> 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.
> main change:
> for dynamic partitions that has static partition it was
> <destination_dir>/<static_partition>/<staging_dir>/<dynamic_partition>
> changes to
> <destination_dir>/<staging_dir>/<static_partition>/<dynamic_partition>
> or in case of \{hive.use.scratchdir_for_staging}
> <scratch_dir>/<static_partition>/<dynamic_partition>
> the change is due to that hive relies on parsing the path to discover
> partitions.
