Upgrade Nutch to Hadoop 0.7
---------------------------
Key: NUTCH-383
URL: http://issues.apache.org/jira/browse/NUTCH-383
Project: Nutch
Issue Type: Improvement
Affects Versions: 0.9.0
Reporter: Andrzej Bialecki
Assigned To: Andrzej Bialecki
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.
