原因：mapred.task.timeout设置时间过短，如上日志，在200秒左右任务状态没有任何变化，hadoop将该任务kill，并清理临时目录，后续遍找不到临时数据了。

修改参数

<property>
<name>mapred.task.timeout</name>
<value>200000</value>
<description>The number of milliseconds before a task will be
terminated if it neither reads an input, writes an output, nor
updates its status string.
</description>
mapred.task.timeout修改称10分钟600000即可。
