    Description

      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.
