Harish Butani commented on HIVE-6013:
-------------------------------------
You mean set hive.support.quoted.identifiers=none; right?
With it is set to 'column' it will treat it as a literal.
And the query would be: select `a.*` from t1;
You need the back-ticks. Otherwise this will not get past the lexer.
Since 'none' is default setting, i thought the exiting test was enough.

>
> Hive's current behavior on Quoted Identifiers is different from the normal
> interpretation. Quoted Identifier (using backticks) has a special
> interpretation for Select expressions(as Regular Expressions). Have
> documented current behavior and proposed a solution in attached doc.
> Summary of solution is:
> - Introduce 'standard' quoted identifiers for columns only.
> - At the langauage level this is turned on by a flag.
> - At the metadata level we relax the constraint on column names.
