---------------------------------------
I have applied the latest patch to trunk and *still* I cannot start a task
tracker if the the directory does not exist:
10/09/09 00:36:29 WARN mapred.TaskTracker: Task Tracker local can not create
directory: /mnt/data8/mr20
10/09/09 00:36:29 WARN util.MRAsyncDiskService: Cannot create toBeDeleted in
/mnt/data8/mr20. Ignored.
10/09/09 00:36:29 ERROR mapred.TaskTracker: Can not start task tracker because
java.io.FileNotFoundException: File /mnt/data8/mr20/toBeDeleted does not exist.
