stack commented on HADOOP-414:
------------------------------
On adding a base abstract ImplicitVersionedWritable, I can see how injection of
application version can be done easily for application-specific Comparables --
as is done above for the DFS-specific DatanodeID class -- but I'm wondering how
would the version be injected when an application uses generic Comparables
such as BytesWritable? Would an application have to pass its version on every
instance creation? E.g. 'new BytesWritable(byte [] b, int version)'?
