Currently, the map/reduce key for vector data is a LongWritable, and the GeoWave record reader assigns that value based on what is returned by SimpleFeature.getID(). It is hard-coded to recognize a string containing one period and the feature id after the period. However, this will not be appropriate for all GeoWave data sources. Look into:
- Seeing if we can set the key to a record number rather than trying to use the feature's id
- Switching the LongWritable map/reduce key to Text (which will be a lot more work)

Since the map/reduce key is not used for processing in MrGeo, I hard-coded the key for GeoWave data to -1. This is also what happens in CsvInputFormat.
