[jira] Created: (MAPREDUCE-1453) Enforce the distinction between MapReduce kernel and library code

Enforce the distinction between MapReduce kernel and library code
-----------------------------------------------------------------

                 Key: MAPREDUCE-1453
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-1453
             Project: Hadoop Map/Reduce
          Issue Type: Improvement
            Reporter: Tom White
             Fix For: 0.22.0


Currently MapReduce kernel and library code are in the same source tree which makes it possible to inadvertently introduce dependencies on the library by the kernel. With MAPREDUCE-1452 it makes sense to enforce the compile-time dependencies (library depends on kernel, but not vice versa), by having two source trees.
