Michael Bieniosek updated HADOOP-2297:
--------------------------------------

    Attachment: Capture.java

Hey Edward,

I think I figured out how to suppress System.exit and capture stdout/stderr.  

Here, System.exit throws a SecurityException, which can be caught above.  In 
this case, I catch in Thread.UncaughtExceptionHandler since I am running 
misbehaved threads.  

I also wrote a class that captures stdout/stderr.  Since java only lets me set 
one printStream to capture stdout per jvm, I have to check 
Thread.currentThread, and then decide where to write the captured output.

I am hoping to incorporate some of this code into my custom jetty server that 
submits hadoop jobs.
