We should actually do this in our lifetime. How about:

mapreduce.server.{common,jobtracker,tasktracker}
mapreduce.child.{common,map,reduce}
mapreduce.client
mapreduce.common

> The mapred package has gotten too big, so I propose changing it to split it into parts.
> I propose the following splits:
> org.apache.hadoop.mapred = client API
> org.apache.hadoop.mapred.task = code for task tracker
> org.apache.hadoop.mapred.job = code for job tracker
> org.apache.hadoop.mapred.utils = non public code that is shared between the servers
> Does anyone have any other divisions that would help?
> I would make the classes sent through RPC public classes in the server's package.
> Thoughts?
