Amareshwari Sriramadasu commented on MAPREDUCE-849:
---------------------------------------------------

I propose, we add following interfaces for cluster configuration keys
{code}
public Interface org.apache.hadoop.mapreduce.Configs {
// holding cluster level configs keys.
}

public Interface org.apache.hadoop.mapreduce.server.jobtracker.JTConfigs {
// holding jobtracker config keys
}

public Interface org.apache.hadoop.mapreduce.server.tasktracker.TTConfigs {
// holding tasktracker config keys
}
{code}

All job-level keys will be added to org.apache.hadoop.mapreduce.JobContext as 
public static String.
These new names will be used everywhere in the framework.

Thoughts?
