The task tracker should track disk space used, and have a configurable cap
--------------------------------------------------------------------------

         Key: HADOOP-336
         URL: http://issues.apache.org/jira/browse/HADOOP-336
     Project: Hadoop
        Type: Improvement

  Components: mapred  
    Reporter: eric baldeschwieler


We've been having problems where the task tracker is destabilizing HDFS by filling \
disks and then releasing them.  Various tasks can also interfere with each other this \
way.

We should have a configurable max working space for a task (and allow the setting of \
lower per task limits).  The task tracker should track use against this limit and \
terminate a job if it overruns it.
