-------------------------------
Status: Patch Available (was: Open)
> Don't call DistCp.execute() instead of DistCp.run()
> ---------------------------------------------------

> Key: HIVE-13704
> URL: https://issues.apache.org/jira/browse/HIVE-13704
> Project: Hive
> Issue Type: Bug
> Components: Hive
> Affects Versions: 2.0.0, 1.3.0
> Reporter: Harsh J
> Assignee: Sergio Peña
> Priority: Critical
> Attachments: HIVE-13704.1.patch

>
> HIVE-11607 switched DistCp from using {{run}} to {{execute}}. The {{run}}
> method runs added logic that drives the state of {{SimpleCopyListing}} which
> runs in the driver, and of {{CopyCommitter}} which runs in the job runtime.
> When Hive ends up running DistCp for copy work (Between non matching FS or
> between encrypted/non-encrypted zones, for sizes above a configured value)
> this state not being set causes wrong paths to appear on the target (subdirs
> named after the file, instead of just the file).
> Hive should call DistCp's Tool {{run}} method and not the {{execute}} method
> directly, to not skip the target exists flag that the {{setTargetPathExists}}
> call would set:
