Review request for hadoop-mapreduce and Todd Lipcon.
Summary
-------
Used the makeComputingMap from Guava's MapMaker to provide a thread safe way of
creating a RecordWriter cache.
For some reason, the map is not really caching it and is instead trying to
apply() over and over again for the same key-value pairs.
This addresses bug MAPREDUCE-1347.
http://issues.apache.org/jira/browse/MAPREDUCE-1347

Testing
-------
Added a test case, but it fails with the current behavior of MapMaker's
makeComputingMap() (would pass if its alright)
Thanks,
Harsh
