Subject common error in map tasks
Date Mon, 22 Apr 2013 08:34:05 GMT

regardless of what job I run, there are always a few map tasks that fail 
with the following, very unhelpful, message: ( that is the entire error 

java.lang.Throwable: Child Error
	at org.apache.hadoop.mapred.TaskRunner.run(TaskRunner.java:271)
Caused by: java.io.IOException: Task process exit with nonzero status of 126.
	at org.apache.hadoop.mapred.TaskRunner.run(TaskRunner.java:258)

I would appreciate it if someone could show me how I could figure out 
why this error keeps happening.
