Owen O'Malley resolved HADOOP-106.
----------------------------------

    Resolution: Won't Fix

I agree with Eric. This is backwards. You want the sequence file to pad out to block boundaries.

> If data blocks were starting and ending on data record boundaries, and not in random places within a file, it would give some important advantages:
> * it would be possible to avoid "fishing" for the beginning of first record in a split (see SequenceFile.Reader.sync()).
> * it would make recovering from DFS errors much more successful and easier - in most cases missing blocks could be just skipped and the remaining parts combined together.
