possible to use mapfiles from dumbo?

[Zak Stone]

One more question for today: is it possible for Dumbo jobs to work
with Hadoop's indexed MapFile format?

http://hadoop.apache.org/core/docs/current/api/org/apache/hadoop/io/MapFile.html
http://hadoop.apache.org/core/docs/r0.18.3/api/org/apache/hadoop/mapred/MapFileOutputFormat.html

If not, how difficult would it be to add this capability?

Thanks,
Zak
