Aihua Xu commented on HIVE-12505:
---------------------------------
+1 on the new patch. I feel we should trash the oldPath when oldPath is not
subdir of destf since currently we lose the capability to bring the old data
back for such case, but this is not related to this jira. We can have a
followup if we see this as an issue.
