      Description

      This is a map-reduce based test that checks consistency of the file system
      by reading all blocks of all files, and detecting which of them are missing or corrupted.
      See HADOOP-95 and HADOOP-101 for related discussions.

      This could be an alternative to the sequential checkup in dfsck.
      It would be nice to integrate distributed checkup with dfsck, but I don't yet see how.

      This test reuses classes defined in HADOOP-193.
