Fix average progress calculation in speculative execution of maps + fix pending issues in speculative
execution of reduces
--------------------------------------------------------------------------------------------------------------------------

                 Key: HADOOP-741
                 URL: http://issues.apache.org/jira/browse/HADOOP-741
             Project: Hadoop
          Issue Type: Bug
          Components: mapred
            Reporter: Sanjay Dahiya


This issue addresses following  
1. Avg progress in speculative execution of map tasks should not divide / maps.length again
in JonInProgress.java:331
2. Normal tasks should get priority over speculative tasks in reduce. JobInProgress.findNewTask
should not break if a spec task is found. 
3. Delete directories used by PhasedFileSystem irrespective of whether speculative execution
is enable to allow tasks to use PhasedFileSystem independently.
