Eric Hanson commented on HIVE-4592:
-----------------------------------

Another issue is that output Long column vectors should have 1 in the data 
vector, and output Double column vectors should have NaN in the data vector. 
Adding tests and fixes for this.
                
> 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.
