-------------------------------
Summary: Insert overwrite should not delete the original directory
Key: HIVE-7092
URL: https://issues.apache.org/jira/browse/HIVE-7092
Project: Hive
Issue Type: Bug
Reporter: Szehon Ho
Assignee: Szehon Ho
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.
