A new example to do tile placements using distributed dancing links
-------------------------------------------------------------------

                 Key: HADOOP-1413
                 URL: https://issues.apache.org/jira/browse/HADOOP-1413
             Project: Hadoop
          Issue Type: Improvement
          Components: examples
            Reporter: Owen O'Malley
         Assigned To: Owen O'Malley
             Fix For: 0.14.0


During a Yahoo Hack Day last year, I wrote a distributed pentomino solver that used map/reduce
and Knuth's dancing link algorithm to solve pentomino tile placement problems. As a side benefit,
I also wrote a sudoku solver using the dancing link library, but the sudoku solver is so fast
that there is no need to distribute it. Anyways, I think it makes an interesting example of
how to do some interesting cpu-heavy distribution in Hadoop.
