-----------------------------------------------------
Key: HADOOP-1991

Project: Hadoop
Issue Type: Bug
Components: mapred
Reporter: Koji Noguchi
Priority: Minor
Fix For: 0.16.0
We had a job filling up one particular drive (different bug) that resulted in
all the subsequent tasks on that node to fail with
java.io.IOException: Mkdirs failed to create

It'll be nice if localization also uses localdirallocator to utilize multiple
disks.
