Veena Basavaraj commented on SQOOP-1901:
----------------------------------------

there is common code that can be moved to the base class, think about it, will 
send a patch for sure, just want to give you headsup, since I know if I put in 
any refactoring in the feature patch, this whole community frowns on it.!

Also do you agree on this point, so that I want to be on the same page
>>
The only extra code in a AvroIDF I want to add it how I convert from Avro to 
ObjectArray and vice versa of course.


> Supporting DRY code in new IDF impementations

> As the title suggests, we want to encourage DRY code in the new IDF 
> implementations.
> As the IDF api mandates CSV and object format for all its sub implementation, 
> I propose we move the common functionality to the base IDF class so that JSON 
> IDF or AvroIDF does not have to repeat this code.
> The only parts of the code that needs to be in subclasses is how then handle 
> the conversion between the "T" ( generic parameter) and the csv/ object 
> representations.
> I saw that http://ingest.tips/2014/12/11/sqoop-1-99-4-release/ mentions 
> extensind from CSVIDF and this cannot technically work since we have the 
> generic T that will be different for AvroIDF or JSON IDF
> Update:
> Also extending from CSVIDF seems a bit ilogical, since the IDF API says that 
> it needs CSV and object Array, these functionality of converting between the 
> two i.e text to object and object to text should be in base class.
