John Sichi commented on HIVE-2330:
----------------------------------
It might be possible to write a hook to accomplish this.
> Allow tables to warn on querying

> It would be excellent if I could set a TBLPROPERTY like "motd" or "motq" that
> means "message of the query." This message would then actually print to the
> CLI or stderr whenever the table was queried.
> Use cases: Warning people that they are querying a deprecated table, or
> warning people that the table they are querying has sensitive information, or
> that it is probably already aggregated somewhere.
