      Improved TaskTracker blacklisting strategy to better exclude faulty tracker from executing tasks.

      Description

      When running a batch of jobs it often happens that the same tasktrackers are blacklisted again and again. This can slow job execution considerably, in particular, when tasks fail because of timeout.
      It would make sense to no longer assign any tasks to such tasktrackers and to declare them dead.
