--------------------------------
Summary: 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
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.
