Okay. It actually looks like the job outright failed. I'll look at

I've looked into this a little bit more. There are some errors that
appear in the job status page under failures. For these jobs, it's
easy
to see the exception that caused the problem. However, there are
other
jobs that fail, leaving Error blank. When I go to the tasktracker log
file, I can see the exception:
INFO org.apache.hadoop.mapred.TaskRunner: task_0002_m_000000_0
java.nio.charset.MalformedInputException: Input length = 14
at org.apache.hadoop.io.Text.validateUTF8(Text.java:477)
It's funny that some failures show the full error on the jobfailures
page, while others leave a blank field.
Anyway, I thought I should bring this to your attention.
This is likely fixed by the patch for HADOOP-293, if you aren't
running the current subversion head. If you find other cases where
the log has an exception and the web ui doesn't, please file a bug on
it and include the call stack from the log.
Thanks,
Owen
