[wankunde]

What changes were proposed in this pull request?

Now the BufferSegment class and FileBasedShuffleSegment class both six fields, represents a segment.

  private long blockId;
  private long offset;
  private int length;
  private int uncompressLength;
  private long crc;
  private long taskAttemptId;

To add a new ShuffleSegment to replace these two class can make the code easier to maintain.

Why are the changes needed?

To simplify the code.

Does this PR introduce any user-facing change?

No.

Sorry for the late reply. @wankunde

Thanks for proposing this. Actually the ShuffleSegment has been introduce to be as the an abstract class. And I think the initial design is to clarify the client/server side shuffleSegment. But I agree with the same part 6 variables should be defined in the existing ShuffleSegment. And there is no need to make the invoking side to use the ShuffleSegment to replace all the Filebased or Buffer segnment.
