using <UTF8, CrawlDatum> to the new format <Text, CrawlDatum>.

>
> Upgrade Nutch to Hadoop 0.7, and replace all occurences of UTF8 with Text.
> UTF8 is deprecated and its use is discouraged due to its limitations.
> This change will break API, in the sense that all third-party additions will
> have to be updated to use new APIs that use Text instead of UTF8 in method
> parameters.
> This change also breaks backward compatibility of data in CrawlDb, LinkDb and
> segments. A tool to upgrade CrawlDb, LinkDb and segments can be created to
> facilitate the upgrade path.
