> The operation {{div}} returns always long. This came from Hive's behavior,
> which is different to the one of most of other DBMS (eg. MySQL, Postgres)
> which return as a datatype the same of the operands.
> This JIRA tracks changing our return type and allowing the users to re-enable
> the old behavior using {{spark.sql.legacy.integralDiv.returnLong}}.
> I'll submit a PR for this soon.
