> When we create local indexes on functions then while joining back missing 
> columns from data table is generating wrong data row key. 
> When we generated index row key schema we are initializing isNullableToBe to 
> true always even if the expression might be not null. Because of this we 
> might change the column type to other castable one and may consider actual 
> data as separator bytes.

>                 Expression e = expressionItr.next();
>                 isNullableToBe = true;
