Subject [jira] Updated: (CASSANDRA-342) hadoop integration
Date Thu, 20 Aug 2009 06:51:15 GMT


Jeff Hodges updated CASSANDRA-342:

    Attachment: 0003-CASSNADRA-342.-Adding-the-WordCount-example.patch

0001) Provides a few changes needed to support the new Hadoop bridge. Specifically, StorageProxy.getKeyRange()
becomes public, RowSerializer becomes accessible to the hadoop package classes, and Token#originalToken()
is added.

0002) This adds the actual Hadoop bridge code. It includes subclasses of InputFormat, RecordReader,
and InputSplit. It also provides a nice RowWritable class to be used as the value passed to
a map. This is also the commit that adds the really nasty boot up code in the class BootUp.

0003) This just adds a simple WordCount example of the Cassandra/Hadoop bridge.
