      Moved Task log cleanup into a separate thread in TaskTracker.
      Added configuration "mapreduce.job.userlog.retain.hours" to specify the time(in hours) for which the user-logs are to be retained after the job completion.

      Moved Task log cleanup into a separate thread in TaskTracker. Added configuration "mapreduce.job.userlog.retain.hours" to specify the time(in hours) for which the user-logs are to be retained after the job completion.

      Description

      Task logs' cleanup is being done in Child now. This is undesirable atleast for two reasons: 1) failures while cleaning up will affect the user's tasks, and 2) the task's wall time will get affected due to operations that TT actually should own.
