             Summary: hive MoveTask cannot show the correct exception message
                 Key: HIVE-27688
                 URL: https://issues.apache.org/jira/browse/HIVE-27688
             Project: Hive
          Issue Type: Bug

Setting hive.load.data.owner to hive.

When I try to insert overwrite to an existing table partition, I get the 
exception that: Unable to move source /path/to/source to destination 
/path/to/dest, which is a very regular error message, gives me no helpful 
information.

But when I try to insert into an existing table partition, I get the exception 
that: Unable to move source /path/to/source to destination /path/to/dest as the 
file is not owned by hive and load data is also not ran as hive. which gives me 
a very helpful error message that I should change the hive.load.data.owner to 
hive.
