> Per discussion with Doug Cutting on hadoop user mailing around Mar 21,
> thread title "MapFile and MapFileOutputFormat". Currently, there is no way 
> to change the index interval for the output MapFile in a map-reduce job.
> As suggested, adding a static method MapFile(Configuration, int) to set the
> index interval and stores in Configuration, then MapFile.Writer constructor
> reads the setting from configuration may be a good idea. 
> I also noticed that Hbase did similar things in HBASE-364.
