Vineet Garg created HIVE-18797:
----------------------------------

             Summary: ExprConstNodeDesc's getExprString should put appropriate 
qualifier with literals
                 Key: HIVE-18797
                 URL: https://issues.apache.org/jira/browse/HIVE-18797
             Project: Hive
          Issue Type: Improvement
            Reporter: Vineet Garg
            Assignee: Vineet Garg


e.g. instead of just {{2016-01-23 00:00:00.0)}} it should be 
{{TIMESTAMP'2016-01-23 00:00:00.0)'}}.
This method is used by explain task and also HIVE-18726 needs it to reparse the 
string for default value.

I am creating a separate ticket for this instead of lumping it with HIVE-18726 
because this will need quite a few golden files update.
