----------------------------

             Summary: More Friendly Error Message after hawqregister with original table
                 Key: HAWQ-1166
                 URL: https://issues.apache.org/jira/browse/HAWQ-1166
             Project: Apache HAWQ
          Issue Type: Sub-task
          Components: Command Line Tools
            Reporter: hongwu
            Assignee: Lei Chang


After hawqregister, if users access the original table, he will get message below. Although this is a undefined behavior, should we write some record into catalog table to return instructive error message in this case?

`
