Ashutosh Chauhan commented on HIVE-13997:
-----------------------------------------
In that case I think it might be better to have this delete logic in
moveFileInDfs() since moveFile() is also called by loadPartition()/loadTable()
and introducing new calls to NameNode will hurt perf for those cases. Also, do
we need recursive delete, won't deleting parent dir be sufficient?
> Insert overwrite directory doesn't overwrite existing files

> Can be easily reproduced by running {{INSERT OVERWRITE DIRECTORY}} to the
> same dir twice.
