Subject Unusual Failure of jobs
Date Mon, 22 Dec 2008 18:24:17 GMT
I have been experiencing some unusual behavior from Hadoop recently.  
When trying to run a job, some of the tasks fail with:

java.io.IOException: Task process exit with nonzero status of 1.
	at org.apache.hadoop.mapred.TaskRunner.runChild(TaskRunner.java:462)
	at org.apache.hadoop.mapred.TaskRunner.run(TaskRunner.java:403

Not all the tasks fail, but enough tasks fail such that the job fails.  
Unfortunately, there are no further logs for these tasks. Trying to  
retrieve the logs produces:


Failed to retrieve stdout log for task:  


It seems like the tasktracker isn't able to even start the tasks on  
those machines. Has anyone seen anything like this before?

We're looking for an Amazing Software Engineers (+ interns):

will award you with $10,007 bailout package if we hire that person.
