> 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
> Fix For: 2.0.1.0-incubating

> 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?
> `
