      This patch removes the following Public Evolving APIs:

      ImmutableBytesWritable Result#getBytes
      void Result#readFields(DataInput)
      long Result#getWritableSize()
      void Result#write(DataOutput)
      static long Result#getWriteArraySize(Result[])
      static void writeArray(DataOutput, Result[])
      static Result[] Result#readArray(DataInput)

      Writable in MR related classes have been replaced with the new Mutation abstract class.
