Ashutosh Chauhan commented on HIVE-6024:
----------------------------------------
This results in inconsistent semantic that while loading from local source
files are *not* moved but copied, but while loading from DFS sources files are
moved and thus are deleted at source location after operation. Ideally same
semantic of move (delete at source) should be provided while loading either
from DFS or local. What exactly should be semantic can be debated, however
scope for this jira is limited to not a create an additional copy task while
loading from local, but rather do the copy (instead of move) in MoveTask itself
and thus saving on unnecessary task execution and FS operations.
