> Add hashUTF8String convenience method to hasher classes
> -------------------------------------------------------
>                 Key: SPARK-23947
>                 URL: https://issues.apache.org/jira/browse/SPARK-23947
>             Project: Spark
>          Issue Type: Improvement
>          Components: SQL
>    Affects Versions: 2.4.0
>            Reporter: Kris Mok
>            Priority: Minor
> Add {{hashUTF8String()}} to the hasher classes to allow Spark SQL codegen to 
> generate cleaner code for hashing {{UTF8String}}. No change in behavior 
> otherwise.
> Although with the introduction of SPARK-10399, the code size for hashing 
> {{UTF8String}} is already smaller, it's still good to extract a separate 
> function in the hasher classes so that the generated code can stay clean.
