HADOOP-2476. Unit test failure while reading permission bits of local
file system (on Windows) fixed. (Raghu Angadi via dhruba)
+ HADOOP-2247. Fine-tune the strategies for killing mappers and reducers
+ due to failures while fetching map-outputs. Now the map-completion times
+ and number of currently running reduces are taken into account by the
+ JobTracker before killing the mappers, while the progress made by the

+ fetch-attempts are taken into account before teh reducer kills itself.
