>
> Today the implementation of "insert overwrite" table or partition deletes the
> entire directory of the table/partition recursively using the HDFS shell
> (-rmr) and then re-creates it.
> This makes it get rid of certain user-set attributes of the directory, like
> permission, owner, group, and will become more important with introduction of
> HDFS extended-ACL's.
