-------------------------------
Summary: Allow use scratchdir for staging
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
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.
