>             Project: Hive
>          Issue Type: Improvement
>          Components: Serializers/Deserializers
>    Affects Versions: 4.0.0, 3.2.0

>       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.
