> 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.
