    A complete rewrite of serialization to Cassandra's OnDiskAtom

    Basically what happened is that now we always read from->to sstable.
    So in the end the output of the reduce can be a compacted table.

    This doesn't take into account the ordering of the sstables as far as
    Cassandra is concerned, so the sstables wouldn't dump back into the db
    without some issues, but there is no reason we couldn't change this.

    Still todo:

    - 1. finish ranged tombstone reduce logic
        This may be done.  Haven't tested it yet, but we are now using Cassandra's code.
    - 2. handle json input
        We will deprecate this.  We could still handle it, but there is no reason to do it
        if we output sstables.
    3. build a testing framework for this as the requirements are difficult now
        Not done, need to build testing for at least the reducer to make sure the new code works.
    4. finish the type handling into json
        This now works, but I now need to allow the job to output json optionally and then extend
        The reader to handle reading sstables, which is what we will want to do internally.
    - 5. Sort input into reduce by type.
        This is now done.  Have to test it, but it appears to work.

    To roll this out in NFLX, besides testing, #4 needs to be done.  Then the python code will have to discount
    the current json snapshot.

    Further work on column based processing.

    Still todo:

    1. finish ranged tombstone reduce logic
    2. handle json input
    3. build a testing framework for this as the requirements are difficult
    now
    4. finish the type handling into json
    5. Sort input into reduce by type.

    I think that is it.  Finally need to do some performance testing on this
    as it seems much slower than the old row code.

    initial commit for handling bad sstables

    I am not at all happy about this change.  The basic idea is to work
    around bad rows by keeping track of where we are in the index files.
    The problem is basically that this mechanism is far reaching and hard to
    test.  Possibly before this can be fully committed we need to bite the
    bullet and create unit tests for the Hadoop features of the code
    (inputformats, splits, recordreaders).
