            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.
