[jira] [Updated] (MAPREDUCE-1638) Divide MapReduce into API and implementation source trees

     [ https://issues.apache.org/jira/browse/MAPREDUCE-1638?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Tom White updated MAPREDUCE-1638:
---------------------------------

    Attachment: MAPREDUCE-1638.patch

> Could the toFullPropertyName method be moved to MRJobConfig and then used by both QueueManager and JobSubmitter? Duplicating it seems ugly.

MRJobConfig is an interface containing constants, so I've created a private QueueConfig class for the toFullPropertyName method instead.

> I think it makes sense to separate the MapReduce source into public API and implementation trees. The public API could be broken further into kernel and library trees.
