Veena Basavaraj commented on SQOOP-1709:
----------------------------------------

If we know for sure that we will not have complex types, lets add a 
AbstractPrimitive class and make sure that the "key" is of that type than a 
generic Column and document the use cases of where this can be a float/ number 
and not just string

> AbstractComplexType changes

> What is the use case for it to have a "key' as a Column type.
> This mean I could have the key as an Array / Map/ Flaoting point? when would 
> this happen, can String not suffice for the key?
> I need details on this.
> Second, for good reasons, we should have a size field to support the 
> collection size.
> Third, Make sure SchemaSerialization class is updated as well with these 
> changes.
