             Summary: Disallow making external tables transactional
                 Key: HIVE-13175
                 URL: https://issues.apache.org/jira/browse/HIVE-13175
             Project: Hive
          Issue Type: Bug
          Components: Hive
    Affects Versions: 2.0.0
            Reporter: Wei Zheng
            Assignee: Wei Zheng


The fact that compactor rewrites contents of ACID tables is in conflict with 
what is expected of external tables.

Conversely, end user can write to External table which certainly not what is 
expected of ACID table.

So we should explicitly disallow making an external table ACID.
