Override automatica final streaming job status message?

Streaming tasks seem to get a final status message from Hadoop itself (not my code) that reports "R/W", presumably the number of records read and written (the number of lines of text I assume).  Problem is, I like to display a final status message for my tasks.  That way I can quickly glance at a list of hundreds of mappers on the job tracker and see a broad survey of their final statuses.  This works fine in an all-
Java job, but in streaming, this R/W status is automatically generated, thus overwriting my final status.

Is there anything I can do about this?

Thank you.

Keith,
  I cant see how you can do it. The status is set in PipeMapred.java
which is the streaming plugin that talks to mapreduce framework and
generated this status message. I cant think of neway of hacking arnd
it except for having your own streaming jar :).

thanks
