He Yongqiang commented on HADOOP-5553:
--------------------------------------
Actually i am trying to skip some bytes of the value part of one record, and
not lazy load.
Is there a possibility to allow SequenceFile to extend to support this?
> Change modifier of SequenceFile.CompressedBytes and
> SequenceFile.UncompressedBytes from private to public

> SequenceFile.rawValue() provides the only interface to navigate the
> underlying bytes. And with some little work on implementing a customized
> ValueBytes can avoid reading all bytes into memory. Unfortunately, the
> current nextRawValue will cast the passing ValueBytes to either private class
> CompressedBytes or private class UnCompressedBytes, this will disallow user
> further extension.
> I can not see any reason that CompressedBytes and UnCompressedBytes should be
> set to private. And since the ValueBytes is public and nextValue() casts it
> to either CompressedBytes or UnCompressedBytes, i think it would be better if
> they are public.
> I am stuck now by this issue, really appracited if this got resolved as soon
> as possible.
