Creating an external table using the 'LIKE' clause actually creates a managed 
table.

                 Key: HIVE-2888
                 URL: https://issues.apache.org/jira/browse/HIVE-2888
             Project: Hive
          Issue Type: Bug
          Components: Metastore
    Affects Versions: 0.7.1
            Reporter: Craig Swift


When creating a new table with both the EXTERNAL and LIKE clauses, the new 
table does not behave as an EXTERNAL table thus resulting in potential data 
loss.

Example:
create external table test1 (VAL string) location '/user/craig/test1';
create external table test2 like test1 location '/user/craig/test2';
drop table test1;

/user/craig/test1 - still exists

drop table test2;

/user/craig/test2 - is deleted (bad)

If I do an extended describe on both tables, test1 shows up as being external 
while test2 is a managed table.
