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.

Thanks for everything.
