thanks. that is the issue, there is no other log files. when i go to the
attempt directory of that failed map task (e.g.
userlogs/job_201304191712_0015/attempt_201304191712_0015_m_000019_0 ) it
is empty. there is no other log file. thou based on the counter value, I
can say that it happens right at the beginning of the map task (counter
is only 1 )

Hi
I have the same problem before
I think this is caused by the lack of memory shortage for map task.
It is just a suggestion,you can post your log

HI
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 message)
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.
thanks,
