Refactor RaidNode to remove dependence on map reduce
----------------------------------------------------
Key: MAPREDUCE-2142
URL: https://issues.apache.org/jira/browse/MAPREDUCE-2142
Project: Hadoop Map/Reduce
Issue Type: Task
Reporter: Patrick Kling
I am refactoring the RaidNode code as follows: The base class RaidNode will
contain the common functionality needed for raiding files. The derived class
LocalRaidNode contains an implementation of RaidNode that performs raiding
locally. The derived class DistRaidNode performs raiding using map reduce jobs.
This way, only DistRaidNode has a dependency on map reduce code and RaidNode
and LocalRaidNode can be moved to HDFS.
