This is an effort to implement a Cassandra Tap for Cascading.

At the moment, only Source is supported, although the tap does automatic

type detection from the CF metadata.

Here's the cascading Wordcount example running on Cassandra:

        Tap source = new CassandraTap("127.0.0.1", 9160, "wordcount", "input_words",

          new Fields("line", "bible"));

        Scheme sinkScheme = new TextLine(new Fields("word", "count"));

        Tap sink = new StdoutTap();

        // the 'head' of the pipe assembly

        Pipe assembly = new Pipe("wordcount");

        // For each input Tuple

        // parse out each word into a new Tuple with the field name "word"

        // regular expressions are optional in Cascading

        String regex = "(?
