Reducing code duplication in Mumak
----------------------------------
Key: MAPREDUCE-1001
URL: https://issues.apache.org/jira/browse/MAPREDUCE-1001
Project: Hadoop Map/Reduce
Issue Type: Bug
Reporter: Hong Tang
The first release of Mumak (MAPREDUCE-728) introduces some coupling between the
core mapred code with Mumak code. Specifically, New constructors are added to
JobTracker and JobInProgress to allow simulator to subclass and alter JT/JIP
behavior. This could be a code maintenance overhead when new changes have to be
ported to either the added constructors or the simulation subclasses.
It would be nice to refactor the constructors of JobTracker and JobInProgress
to avoid as much code duplication as possible.
