In Hive a varchar is a string that is capable to set a max length. It is still a string:
Varchar
Varchar types are created with a length specifier (between 1 and 65535), which defines the maximum number of characters allowed in the character string. If a string value being converted/assigned to a varchar value exceeds the length specifier, the string is silently truncated. Character length is determined by the number of code points contained by the character string.
Like string, trailing whitespace is significant in varchar and will affect comparison results.
