Earwin Burrfoot commented on LUCENE-2491:

Or we can force the same Codec for the whole index. Which really makes sense.

> I'm trying to implement a Codec that works with append-only filesystems (HDFS). It's
_almost_ done, except for the SegmentInfos.write(dir), which uses ChecksumIndexOutput, which
in turn uses - and seek is not supported on append-only output. I propose
to extend the Codec interface to encapsulate also the details of SegmentInfos writing / reading.
Patch to follow after some feedback ;)
