------------------------------------------

             Summary: Vectorization: Optimize timestamp to string-timestamp comparision using
long comparisons. 
                 Key: HIVE-6776
                 URL: https://issues.apache.org/jira/browse/HIVE-6776
             Project: Hive
          Issue Type: Bug
            Reporter: Jitendra Nath Pandey


The timestamp to string-timestamp comparison currently (HIVE-6752) happens using string-string
comparison because timestamp is cast to string. This can be optimized by casting string-timestamps
to timestamps and using long comparisons instead.
