Subject [jira] Commented: (HADOOP-414) replace class UTF8 with class Text
Date Fri, 15 Jun 2007 22:03:27 GMT

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)'?

> Since class UTF8 is deprecated, all references of UTF8 in hadoop should be replaced with
class Text if the change does not break the system.
