Jitendra Nath Pandey commented on HIVE-4592:
--------------------------------------------
Long-long division is handled specially, as it is cast to double division.
These expressions are no longer generated using templates. Please add the fix
to those too.
They are located in:
ql/src/java/org/apache/hadoop/hive/ql/exec/vector/expressions/
> ColumnArithmeticColumn.txt template never sets output isNull to true; can
> give wrong results
