Eric Hanson commented on HIVE-4592:
-----------------------------------
Let me look at the other templates. I expect I will broaden this to cover other
templates. I fixed the issue in this template ColumnArithmeticColumn.txt
regarding the assumption that noNulls=false and isRepeating=true means all
values are null, which is not a correct assumption.
So, the patch is not ready yet. Wait for another revision.
> ColumnArithmeticColumn.txt template never sets output isNull to true; can
> give wrong results

> ColumnArithmeticColumn.txt should set the output column's noNulls flag to
> true if neither input column has nulls, but it does not do that. This can
> lead to wrong results is the noNulls was set to false in a previous use of
> the batch.
