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.
