[VOTE] Should we create sub-projects for HDFS and Map/Reduce?

[Owen O'Malley]

I think the time has come to split Hadoop Core into three pieces:
  1. Core (src/core)
  2. HDFS (src/hdfs)
  3. Map/Reduce (src/mapred)

There will be lots of details to work out, such as what we do with  
tools and contrib, but I think it is a good idea. This will create  
separate jiras and mailing lists for HDFS and map/reduce, which will  
make the community much more approachable. I would propose that we  
wait until 0.19.0 is released to give us time to plan the split.
