Subject [jira] [Commented] (HIVE-3410) All operators's conf should inherit from a common class
Date Tue, 28 Aug 2012 04:02:07 GMT


Namit Jain commented on HIVE-3410:

I will make the changes/comments.

Kevin, should I call it OperatorDesc ?

Changing the name in the future will not be that difficult, since eclipse should be able to
it. Won't require going through all the code.

> I faced this problem while working on HIVE-3086.
> Wanted to add a common interface to all the operator's confs.
> Currently, the operator signature is Operator<T extends Serializable>,
> which makes it difficult to add more methods to T.
> Created a common interface SerializableCloneable, and now 
> Operator<T extends SerializableCloneable>.
> If we want to add more methods to SerializableCloneable in the future,
> it wont require changing so many files, so submitting it as a separate patch.
