----------------------------
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?
`
