Subject [jira] Created: (HADOOP-2163) mapper failed due to exceptions
Date Tue, 06 Nov 2007 20:06:50 GMT
mapper failed due to exceptions
-------------------------------

                 Key: HADOOP-2163
                 URL: https://issues.apache.org/jira/browse/HADOOP-2163
             Project: Hadoop
          Issue Type: Bug
          Components: mapred
            Reporter: Runping Qi




>From time to time, I observed that mapper tasks failed due to the following exception:
../logs/userlogs/task_200711032036_0145_m_000000_0/stdout (No such file or directory)
	at java.io.FileOutputStream.openAppend(Native Method)
	at java.io.FileOutputStream.(FileOutputStream.java:177)
	at org.apache.hadoop.mapred.TaskRunner.copyStream(TaskRunner.java:400)
	at org.apache.hadoop.mapred.TaskRunner.runChild(TaskRunner.java:432)
	at org.apache.hadoop.mapred.TaskRunner.run(TaskRunner.java:292)

The re-run of the task succeeded. The machine where the task failed seemed to be normal.
