      Description

      Some of the reduces have been stuck for hours looking for 137 map outputs. When I look at the job events all 2600 of the maps have succeeded. There have been lots of lost task trackers and shuffle failures. The maps have been run between 1 to 6 times each. I do see some of the events in the task event log are marked OBSOLETE.
