[jira] [Created] (HIVE-21252) LazyTimestamp - Use String Equals

BELUGA BEHR created HIVE-21252:
----------------------------------

             Summary: LazyTimestamp - Use String Equals
                 Key: HIVE-21252
                 URL: https://issues.apache.org/jira/browse/HIVE-21252
             Project: Hive
          Issue Type: Improvement
          Components: Serializers/Deserializers
    Affects Versions: 4.0.0, 3.2.0
            Reporter: BELUGA BEHR


{code:java|title=LazyTimestamp.java}
    if (s.compareTo("NULL") == 0) {
      isNull = true;
      logExceptionMessage(bytes, start, length, "TIMESTAMP");
    }
{code}

compareTo generates a number to represent the differences between the two Strings.  It's faster to simply call "equals" which will simply compare the two String directly and return a boolean.
