> randomwriter with speculative execution turned 'on' fails with too many
> errors:
> 2006-12-25 06:50:38,880 INFO org.apache.hadoop.mapred.TaskInProgress: Error

> /randomwriter/input/part000522 for DFSClient_task_0002_m_002101_1 on client
> XXX because pendingCreates is non-null.

> /randomwriter/input/part000654 for DFSClient_task_0002_m_002247_1 on client
> XXX because pendingCreates is non-null.
> I suspect this is due to the the fact that randomwriter doesn't use the
> PhasedFileSystem.
